Why Choose North American Industries?
6. Class “D” Heavy Duty Cranes Designed for Twice As Much Work
Compared to class “C” cranes, your class “D” cranes from North American Industries are designed to perform twice
as much work in their lifetimes. We only build cranes with a rating of class “D” or higher. The Crane Manufacturers
Association of America code book specifies:
Class “C” is for Moderate Duty
Class “D” is for Heavy Duty
•
•
There are major design and component differences between
the two classes which provide class “D” cranes with longer
life. Compared to a class “C” crane of a given lifting capacity,
a class “D” crane of the same capacity is designed to:
Make twice as many lifts over its lifetime
Lift the maximum rated load 30% more often
1.
2.
Quality Parts, Quality Design
Reliability is crucial as a quality material handling system will result in higher efficiency and a good return on
investment. It’s important to think long-term. Our cranes will last decades because they are designed to meet
Class “D” or Class “E” standards. Even standard jobs require quality parts and engineering.
Superior parts and design also mean that your equipment will be low maintenance, therefore, saving money
and reducing downtime. See the “Low Maintenance” and “Quality Parts” pages for more detailed information on
the quality construction of our cranes and the features available for them.

North American Industries’ end truck and trolley motors have
Class “F” insulation, which allows the motor to run hot and still
operate properly. Use of Class “B” insulation would cause the
motor to burn out at temperatures that our Class “F” motors
can easily withstand.
The wheels, gears, axles, motors and gear boxes on a Class
“D” crane from North American Industries are physically bigger
and stronger than those used on Class “C” cranes.
Class C Moderate Service (CMAA Definition) - the crane will handle loads which average 50% of the rated
capacity with 5 to 10 lifts per hour, averaging 15 feet, not over 50% of the lifts at rated capacity.
Class D Heavy Service (CMAA Definition) - loads approaching 50% of the rated capacity will be handled
constantly during the working period. High speeds are desirable for this type of service with 10 to 20 lifts per
hour averaging 15 feet, not over 65% of the lifts at rated capacity.

Bridge Cranes

or email info@naicranes.com
.
This type of crane runs on an elevated runway structure along the length of a factory and provides three axis
of hook motion (X, Y, and Z). Both single and double girder bridge designs allow very precise hook positioning
and gentle load placement.
Advantages of a Bridge Crane:
greatest flexibility for hook coverage and control over the load
fewest number of physical obstructions on your factory floor
Double Girder Versus Single Girder:
Based on the CMAA (Crane Manufacturers Association of America) specifications, both single and double
girder cranes are equally rigid, strong, and durable. This is because single girder cranes use much stronger
cross girders than double girder cranes, and single girder cranes have lateral bracing. The real difference
is that double girder cranes typically provide better hook height because the hoist is positioned between the
girders, typically providing an additional 2 to 3 feet of lift.
•
•
Comparison to Forklifts:
Less Product Damage - Forklifts often cause more
damage to the product than overhead cranes. This occurs
especially when forklifts travel over uneven paths and
product must be transported relatively long distances.
Cost Effective Use of Space - Forklifts can only stack
product as high as the mast will elevate. In comparison,
a crane allows for greater hook height and more efficient
use of space. Therefore overhead cranes can eliminate
costs associated with a larger factory or yard for storage.
Less Labor - One crane system with one operator can
replace multiple forklifts proving cranes to be more
efficient. Costs are reduced further because fewer
personnel are required.
Less Maintenance - Heavy use of a large number of
forklifts translates to high maintenance costs. Typically,
forklifts need replacing after several years of this type of
wear. Class “D” cranes from North American Industries
require very little maintenance and are rated for heavy
duty usage. Our cranes are also guaranteed for two years
and are designed to last for decades.
5
Types of Bridge Cranes
Top Running:
An ASCE rail or square bar is installed on top
of the runway beams. The wheels ride on the
rail rather than directly on the runway beam.
Top Runner:
By incorporating a pair of single flange wheels,
the crane can ride directly on top of our runway
beam, without using a costly crane rail. A top
runner, as opposed to a top running crane
can provide substantial savings in eliminating
the need for both purchase and installation of
the crane rail. Top runner cranes are just as
durable and long lasting; they are built to the
same CMAA Class D heavy duty standards for
decades of use.
Due to the loading applied to the flanges of the
runway beam, this design is limited to lighter
capacities, typically 10 tons or less.
Underhung:
The end trucks of the crane ride on the
bottom flange of the runway beam. Typically,
an underhung runway is suspended from the
roof of the building and is available only on
lighter capacities, usually 10 tons or less.

An Increasingly Popular Alternative to Overhead Bridge Cranes
Gantry cranes have become a widely accepted alternative to overhead bridge cranes. This type of crane is similar
to the bridge crane except that it runs on a track at the floor or ground level rather than an elevated runway. The
bridge of the gantry is supported by a pair of rigid steel legs which are carried by a pair of end trucks along the floor
level runway.
can be used either indoors or outside
available in spans to 150 feet and capacities to 150 tons
•
•
North American Industries Specialized Gantries:
Single-Leg Gantry
A combination of the bridge crane and gantry crane. One leg rides on the floor, while the other side’s end truck rides
on an elevated runway beam.
Unique Trackless Gantry
Unlike most gantry cranes, which run on ASCE rails or an inverted
angle iron, North American Industries offers gantry cranes that are
specially designed to allow one leg to ride directly on a smooth
concrete floor. Thus, the cost and travel barriers normally associated
with gantry tracks are eliminated. For applications where a smooth,
clean floor is not possible, or in high capacities, our gantry cranes
can ride on a leveled, 1/2” high steel plate. This floor-mounted
plate provides an alternative to a 4” high rail track and still permits
unobstructed access to the cranes’ work area by forklifts, work carts
and personnel.
Benefits of a Gantry
Space Saving - Can operate in a work-zone
of limited area occupying less work space
Durable - Built to heavy duty Class D
specifications, which meet the demands of
high duty cycles
Adaptive - Can be custom-engineered to
power through and navigate inclines
Less Expensive - May cost less than a
bridge crane
Proven Effectiveness - Have proven
themselves in applications ranging from
New York City’s major bridge projects to the
tunnel-laying of Baltimore’s subway system

A Gantry Crane May Save You Money
Because gantry cranes ride on the ground rather than on overhead runways, they don’t require a runway structure
and they may not require concrete foundations. A typical gantry crane installation is relatively fast and simple.
Depending on the environment and application, gantry cranes can sometimes provide the same material handling
capabilities as a comparable bridge crane system, but with a significant cost savings.
Cost Effective Alternative to Lattice Boom and Hydraulic Cranes
Where once highway and heavy construction contractors would almost exclusively use towers and crawlers for
job site lifts, they are now increasingly turning to overhead cranes for bridge, subway, and tunnel construction
and repair. Gantry cranes....
can be resold for a high return or converted for the next
application
weigh less, placing smaller loads on soil and structures in
the work area
can operate on an active bridge deck
can be powered by diesel generators and manipulated by
radio control, requiring fewer operators and laborers across
an extended workday, resulting in lower operational costs
and safer material handling

This chart shows a typical example of the cost savings
in purchasing a gantry crane instead of an overhead
bridge crane. Please note that this price workup is
only meant to be a demonstrative example of one
instance where a gantry crane is advantageous for
the customer. Contact our sales department for more
information on whether a gantry crane is the best
option for your specific needs.
However, not all Gantry Cranes cost less than their bridge
crane counterparts. A gantry crane is a more cost-
effective alternative if:
1. You are currently in a leased facility and do not want
to make a major investment in a bridge crane runway
structure.
2. You may be planning to move the crane in the near
future and want to take your entire investment with you.
3. You require a crane system that moves loads between
the interior and exterior of your building.
4. You need long runway structures of over 150 feet where
the runway steel and foundation costs are very high.

With a monorail system, the hoist and trolley run on a stationary beam. Because of their inherent speed and
efficiency, monorail systems are an effective method of moving and positioning loads to specific locations. They
are available in capacities up to 150 tons.
Monorails
Types of Monorails:
Our engineering staff can design complex monorail systems
including curved tracks, multiple switches and interlocks
which permit monorails to interface with other material
handling systems. Highly automated monorail systems,
controlled by computers or programmable logic controllers,
are also available.
We design and build supporting structures — both ceiling-
suspended and floor-mounted self-supporting. This allows
us to provide you with the most cost-competitive monorail
system for your facility.
Common Applications:
Monorails are often used for repetitive production jobs, such as paint booths and water treatment plants. Monorails
are best used in applications where materials are to be transported from one fixed point to another fixed location,
or through a process; e.g., painting, blasting, delivering hot metal from the furnace to a fixed pouring location. The
monorail allows two axes of hook movement: up/down and forward/back along the monorail beam. There is no
lateral motion under the monorail beam.
If you need more freedom of movement than a monorail can provide, you may want to consider a bridge crane,
gantry crane, or custom crane. North American Industries sales engineers can help you determine the most
appropriate crane type for your application.

Sometimes a Standard Crane Isn’t the Best Solution
Don’t settle for a standard crane if it doesn’t fit your application. At North American Industries, our engineers
take great pride in their ability to provide customers with the crane that best meets the requirements of
their industry and purpose. North American Industries builds all cranes to the customer’s specifications.
Sometimes those specifications result in a rather standard configuration, but other times, we create an
innovative and unusual design to best suit the needs of the customer.
When you request a crane quote, we always ask your application because at North American
Industries, it is standard practice to make sure you get the most appropriate and cost effective
crane type and features for your individual needs.
Our Qualifications for Building Customized Cranes
We have hands-on experience in very demanding environments requiring special material handling. For
example, we can design cranes for
high duty cycles
tight dimensional constraints
precise placement
long, bulky, or awkward loads
extreme weather conditions
maximizing lift height
hazardous or special environments
systems with multiple cranes working together
In addition, we have met the unique specifications of
government and federal agencies.
If you have a basic idea or concept but don’t know who can finalize it...
Many customers come to us with a basic concept for their handling system: they know what they need and
how it should work, but not how to make it happen. Our designs provide the structural, mechanical and
electrical calculations required to transform their concepts into a finished product. We can do the same for
you, whether it’s troubleshooting a design or fabricating and installing a custom crane system.
If you want a highly specialized, efficient system dedicated to one task...
Many of our customers use specially designed cranes to perform repetitive, high-duty-cycle tasks in the
manufacturing process. If you have a production application which requires a crane to perform one function
very efficiently, very fast, and with a high degree of automation, call us to discuss your application. This is
where our custom designed cranes can make a difference in your business.
Even if you are looking for a standard crane...
Many times it takes only a small modification of a standard configuration to make a great improvement on the
crane’s utility for a particular job.

North American Industries’ engineers designed a 5 ton
custom radial crane for one of our customers with one
side riding on rail around a center pole and the other side
riding on a circular runway. Because the existing building
was circular, the customer wanted a lifting system with a
hoist that could cover the cylindrical area of their facility,
and lift loads up to 30 feet high.
A standard bridge or gantry crane would not have
been able to meet the needs of the customer, so North
American Industries designed a custom solution.
North American Industries has experience designing custom cranes to fit on bridges and elevated highways
to handle the materials necessary for repairs and construction projects.
North American Industries has designed and built cranes for work on the following bridges in NY: Bronx
Whitestone Bridge, the Queens Boulevard Bridge, the Williamsburg Bridge, and the Triborough Bridge.
North American Industries also designed and manufactured a portable crane for work on several bridges on
the Ohio River, and the crane for the I-81 work in Harrisburg, PA.
There was a large amount of customizing involved in the crane designs for each of these projects. Standard
cranes and “off the shelf” material handling equipment certainly would not suffice. In designing, North
American Industries had to consider
weather conditions, inclines, power source,
and limited area among other things.

The Runway Design
North American Industries customers receive the industries’ most cost effective runway structures because we
understand both cranes and runways. We know the crane and runway must both work properly in conjunction to
ensure smooth operation of the lifting system. Some crane companies don’t have the engineering capabilities to
design runways. At North American Industries, we believe that it’s logical that the engineers who design your crane
also design your runway structure. We take into consideration building structural analysis, seismic calculations,
foundation design, and dimensional constraints. Our structural and mechanical engineers utilize CAD systems to
create your runway designs in strict accordance with:
CMAA (Crane Manufacturers Association of America)
AISC (American Institute of Steel Construction)
UBC (Uniform Building Code)
•
•
•
Runway Structures
Fabrication
The same rugged quality that goes into our cranes
is applied to our runway structures. In many cases,
the same craftsman and welders who fabricate your
crane also produce your runway structure.
Installation
A correctly installed runway structure insures you
a smooth running crane system. Our installers are
runway experts. Their vast experience has been
established over many years and thousands of
installations. They have developed unique skills and
special tools that make installations quick and easy.
Technical Tip - Runways Without Foundations
Problem: install new runway system in a working factory, without
causing major impact on ongoing operations.
North American Industries Solution: We studied the design of large
load-bearing concrete foundations under many runways. After
careful engineering analysis, we developed a system that distributes
loads of the crane without having to dig up the factory floor, move
machinery, and disrupt workflow. This is achieved by changing the
runway design to distribute loads placed on the floor.
*Exact calculations are done by North American
Industries for an accurate assessment of each facility.
In some cases, however, floors or system designs
cannot meet all code requirements without installing
foundations.
If you have the skill to fabricate and install the runway structure, we can supply you:
runway design, fabrication drawings, foundation sizes, and assembly instructions. All of our designs are available
with the engineering calculations required to obtain local building permits or professional engineer certification.
If you require a long runway... we suggest you also evaluate a gantry crane - it may be a less expensive and
more appropriate solution.

1. Complete Crane
This option is just as it sounds. We build the whole crane.
It typically consists of hoist, trolley, end trucks, electrification systems, controls, and cross girder(s). We fully
assemble, wire, and test the crane’s bridge assembly and its electrical components in our factory. (The crane
may be disassembled for shipping purposes.)
2. Component Crane
The hoist, trolley, end trucks, electrification systems, and controls are shipped fully assembled, tested, and
painted. Trolleys and underhung end trucks are preset to your exact flange adjustment. We provide most
of the assembly required to build a crane when you purchase a component package. All you provide is the
structural steel for the cross girder(s) and a few inexpensive small angles and steel plates. Our component
crane includes all the remaining parts needed for assembly. We can also provide:
Detailed Assembly Instructions
Cross Girder Specifications so you can purchase the correct beam from a local steel supplier
Detailed Runway Design Drawings and specifications to allow you or a local contractor to fabricate
and install your runways
Comprehensive Installation Instructions in easy to follow steps
24/7 Toll Free Help Line so your North American Industries project manager can provide quick
responses to your assembly or installation questions. We are available after hours if you need to
discuss your project with us right away. We understand the importance of effortless communication
and excellent customer relationships.

You will need to understand basic crane installation concepts if
you choose the component crane option. You should be able to
follow our assembly instructions if you have basic electrical and
metal fabrication skills, such as welding or bolting parts together.
If questions do arise, you can reach your North American
Industries project manager on our 24/7 toll free help line.
You save on shipping costs as well as final assembly costs.
3. The Kit Crane
This option reduces your costs even further if you want to do more of the assembly. You get the end trucks and
trolley in parts form—such as wheels, axles, bearings, gears, and motors. We provide all machined parts, all
control panels fully wired, and all purchased components, except the simple structural steel shapes. You need
experience in simple machine assembly, and you will need the machinery to cut, burn, and drill steel. As with
the Component crane, North American Industries provides complete drawings, detailed instructions, and toll-
free telephone support to make your work easier. You can reduce your costs and still get a high quality crane.

North American Industries normally performs load tests prior to start up, tuning the crane for peak operating
efficiency, conducting operator training and providing instruction on basic maintenance procedures.
1. We Do a Turnkey Installation
Our expert staff does everything. We have the tools and experience to make the job completely hassle-free.
Note: Typically, we do not provide test weights, but arrangements can usually be made for special requests.
2. You Provide Some or All of the Manpower
This option will reduce your costs as compared to a turnkey installation.
We provide a working supervisor, who brings all the major equipment needed (
the customer typically provides
their own employees with personal hand tools). The working supervisor works alongside your employees,
directing them as his helpers to install your crane. North American Industries takes complete charge of the
process and ensures a smooth installation. Best of all, if you choose to provide some helpers, they are sure to
learn a great deal about crane operation and maintenance.
Possible customer savings: $5675 (from the example in the cost comparison chart below)
3. You Provide Some or All of the Equipment
If you have the necessary welding apparatus, forklifts, and man-lifts, you can save money by letting us use your
equipment. Our people still do all the work, and bring our specialized tools to you.
Possible customer savings: $6765 (from the example in the cost comparison chart below)
4. You Provide Manpower and Equipment
Of all the choices, this option provides the most savings. In the example below, costs are reduced by more
than 65%. With this option, North American Industries still takes complete charge of the process and ensures
a smooth installation, but you save even more money. We provide a working supervisor who directs your
employees to use your welding apparatus, forklifts, and man-lifts.
Possible customer savings: $12,445 (from the example in the cost comparison chart below)
Review and Start-up Service
If you choose to install your crane yourself, you can also hire our installation specialists to review your
installation, and make sure that your crane operates safely, reliably and meets all codes. These services are
available on a daily rate basis.
Note: These prices are only meant for the purpose of demonstrating the example.
North American Industries has installed cranes around the world, and we are continually investing in state-of-
the-art laser alignment instrumentation, custom-built rail jigs, adjustable runway tie-backs, and other specialized
tools designed to provide clean, accurate, and quick installations.

2. Bearings Won’t Wear Out Quickly
We use a minimum of 2 bearings / wheel. All bearings
have a minimum life expectancy of 10,000 hours,
which is double the Class “C” rating. Cranes built
by North American Industries use bearings that are
sealed-for-life and never need lubricating.
3. Automatically Resetting Overloads
Our cranes use automatically resetting thermal
overloads, instead of fuses that would need to
be replaced. These overloads are placed inside
all 3 motor windings to assure the most accurate
measurements.
4. Durable Pendant and Pendant Cable
The pendant is constructed of nearly indestructible,
lightweight composite thermoplastic material with 2
steel wires built into the cable jacket for permanent
strain relief. North American Industries understands
that the pendant cable needs to be durable enough
for every day use with all kinds of demanding
applications. Our cables are able to handle the strain.
For added protection against breakage, the wires
in the cable all lay straight, and are never spiral
wrapped.
5. Contactors Never Need Replacing
Our contactors, rated for 20,000,000 stop / start
cycles if used in conjunction with inverters or
electronic soft start features, should never need
replacing under normal operating conditions.
6. Protection Against Wire Breakage
You receive approximately 15% spare conductors for
our bridge electrification cable and our pendant cable.
If a wire breaks, you don’t have to replace the cable,
just connect the spare conductor.
7. Gearbox Oil Never Needs Changing
Gearbox operates in a totally enclosed system with
high grade synthetic oil that never needs changing.
8. Easy Access for Inspection or Repair
Our cranes are designed to allow for quick inspection
or repairs when needed. Our wheels can be removed
from above; you do not have to lift the crane off the
runway rails. Our electrical panels are not crowded,
and the wiring diagram is mounted inside the panel.
1. Reliable Braking System
North American Industries uses mechanical brakes that typically never need adjusting or replacing. Our
mechanical brakes prevent the following problem that can occur with electric motor brakes:
Crane Travels Too Far Before Stopping?
If your crane coasts more than a few feet, then it is likely that it uses electric motor brakes and
that the brake pads haven’t been replaced (they require replacing or adjusting every 1-2 years).
If they are not changed, the crane rolls 10 to 20 feet before stopping. The operator, in turn,
learns to reverse the crane to stop it. This “Reverse Plug” will damage the gearbox.
In contrast to electric motor brakes, North American Industries’ mechanical brakes provide a gentle, consistent
coasting stop that does not vary over time. For cranes that travel over 100 FPM or require quick stopping, we
suggest considering the soft-stop feature of a variable speed inverter.

Parts Availability & Service
North American Industries has a wide selection of replacement parts in stock to meet any demand. We
supply parts for all our cranes as well as parts from all major hoist manufacturers.
No matter who the original crane manufacturer was, North American Industries
can supply parts that are compatible.
Our Parts Department understands your needs and is available 24 hours/day, 7 days a week on our
customer service hotline to supply you with replacement parts as fast as possible.
Vendor Managed Inventory (VMI)
Vendor Managed Inventory is part of North American Industries’ efforts to provide convenience
and speedy service to customers. North American Industries’ parts department sends customers a
Recommended Parts List at the beginning of the warranty period (or you can request a Recommended
Spare Parts List at any time). The customer can buy the recommended parts to keep on their shelf.
If a part fails, it can be replaced immediately with the part on hand. If the customer does not have the
capability of swapping parts, North American Industries can demonstrate during a CRISP inspection or a
service company can be called in without delay.
Meanwhile, the customer calls North American Industries for an RMA (Return Materials Authorization),
sends the part back for evaluation and if it is covered under warranty, we send a replacement part at no
charge. This process eliminates the problem of a customer’s operation being immobilized while waiting for
a new part to be shipped. North American Industries offers VMI because it can be invaluable in minimizing
costly downtime for the customer.

Single Girder or
Double Girder?
A common misconception is that double girder
bridge cranes are more durable.
Based on the CMAA (Crane Manufacturers Association of America) specifications, both single and double
girder cranes are equally rigid, strong, and durable. This is because single girder cranes use much stronger
cross girders than double girder cranes, and single girder cranes have lateral bracing.
The Difference is in the Hook Height
The principle difference between single and double girder
cranes is hook height (how far above the floor your hoist
will lift). Double girder cranes provide better hook height.
Double girders typically allow 18-36 inches higher lift.
Double girder cranes can provide more lift, because the
hoist is placed between the cross girders rather than under
them. Therefore, the depth of the cross girder is gained in
switching to double girders.
Cost Considerations
Single girder cranes may cost less for several reasons:
Only one cross girder is required
The trolley is simpler
Fright expenses are reduced
Installation is faster
Runway beams are lighter
However, not all cranes should be designed with a single girder...
•
•
•
•
•
Single girder cranes have been built in spans over 100 feet
and capacities of over 100 tons but typically cost effective
engineering dictates that single girder cranes be considered
as per the chart.
Ultra Low Headroom (ULH) trolleys
Double girder cranes typically have the hoist and trolley
riding on top of the cross girders. As an option, we can
provide a trolley that rides between the cross girders.
This may be appropriate if:
maximum hook height is required
your cross girders, as well as your hoist, must be
the maximum height above the floor
you must minimize the distance above your
runway beam
you need the crane to be more compact

Electric Chain or
Wire Rope Hoist?
Consider your application and requirements (such as speed,
cost, and precise placement) before choosing a hoist type.
The technology for hoists is always improving. Chain hoists have become more durable, and new hoists are
designed with lower headrooms. Currently, both electric chain and wire rope hoists are appropriate for typical
factory applications in capacities to 7.5 tons.
Chain hoists...
lift by the chain passing over a lift-wheel and
depositing the chain into a chain container
require less maintenance
tolerate greater levels of abuse
provide more allowance for “side pulling”
are less expensive
provide true vertical lift
are more common for applications below 7.5 tons
•
•
•
•
•
•
•
Both chain and wire rope hoists are rated H-4 (heavy duty) or H-3 (moderate duty). Duty ratings are a better
indicator of hoist durability than hoist type (chain or wire rope). Both types of hoist use similar motors, brakes
and controls. The main difference between electric chain hoists and wire rope hoists is in the design of the lifting
mechanism. Be sure to request an H-4 rating on either hoist type to ensure long life and low maintenance.
Consider an electric chain hoist up to 7.5 ton
capacity for the following:
8-10 hours per day use
10-20 lifts per hour
Less than 30 minutes motor on time/hour
High percentage of lifts at full capacity
True vertical lift at no extra cost
High durability at low cost
•
•
•
•
•
•
What is True Vertical Lift?
“True Vertical Lift” refers to lack of any lateral hook drift as the hook moves vertically throughout the full range of
motion. Many wire rope hoists are designed with a single part of cable coming off of the hoist drum, which then
is reeved through upper and lower sheaves until it dead ends back on the hoist body. As the hook is raised, the
cable spools across the drum causing slight lateral movement of the hook, generally in the range of ¼” lateral
movement for every 12” of vertical movement. In most applications, this lateral drift is no problem, however, in a
few applications; this lateral movement can result in damage to product, or worse, damage to valuable tools and
fixtures. Wire rope hoists are available in both single reeved and double reeved (true vertical lift) configurations. In
the lower capacities (below 30 tons) you will often pay a premium for true vertical lift so it is important to understand
if you really need this feature. As an alternative to wire rope hoists, all chain hoists provide true vertical lift by the
nature of their design, i.e. a chain passing over a lift wheel rather than spooling across a rope drum. Chain hoists
are generally available in capacities up to 20 tons and may represent an economically attractive alternative to wire
rope hoists.
Your sales engineer at North American Industries can advise on the best hoist for your application.

Crane Components
All of our bridge and gantry cranes can be purchased in cost saving component form. The component
package includes all the same top quality Class “D” equipment as our complete cranes. The only
difference is that with a component package, you purchase the structural steel cross girders from a
local supplier and perform some final assembly labor.
We provide:
1. Hoist
2. Trolley
3. End Trucks
4. Bridge Electrification
5. Runway Electrification
You provide:
Cross Girder, which is a single or double
structural steel beam from which the hoist and
trolley hang
The hoist, trolley, end trucks, electrification systems, and controls are already tested, and painted when
you receive them. Trolleys and underhung end trucks are preset to your exact flange adjustment. When
you purchase a component package, we provide most of the assembly required to build a crane. The
only parts the customer must obtain independently are the structural steel for the cross girder(s) and a
few inexpensive small angles and steel plates. Our component crane includes all the remaining parts
needed for assembly. We can also provide:

Class C vs. Class D
The superior durability of a Class “D” crane provides a longer
operational life and lower maintenance costs.
The Crane Manufacturers Association of America (CMAA) has issued over 150 pages of specifications
detailing how to design and build cranes of differing classifications. An extensive list of more than 50
components (wheels, bearings, motors, axles, contactors, etc.) are upsized for each successive crane
class, which means that parts on a Class “D” crane are physically bigger and stronger than parts on a Class
“C” crane. Crane designs are strictly regulated by the CMAA and must be documented by engineering
calculations.
Compared to a Class “C” crane of equal
lifting capacity, CMAA specifications dictate
that a Class “D” crane is designed to:
Make twice as many lifts over its lifetime
Lift the maximum rated load with 30%
greater frequency

2.
What Are Some “Heavy Duty” Applications?
Precast Concrete
Stone, Marble, and Granite Fabrication
Shipbuilding
Steel Fabrication
Metal Stamping
Bridge Construction
Foundries
Steel Service Centers
Why Choose Class “D” Heavy Duty?
While there are six classifications ranging from Class “A” (standby) to Class “F” (continuous severe),
the majority of industrial crane applications call for either Class “C” or Class “D”. Class “C” cranes are
designed for moderate duty applications and Class “D” cranes are designed for heavy duty applications.
However,
Class “C” applications can be accommodated with either a Class “C” or a Class “D” crane.
There are several important benefits to using a Class “D” crane for what might be considered a Class “C”
application...
Purchasing a Class “D” crane for a Class “C” application will extend the crane’s operational life (lasting up
to 40 years), minimize maintenance, reduce down time, and significantly improve margins of safety. Many
customers find that the Class “D” crane is often the more cost effective choice.

Class C Moderate Service (CMAA Definition) - the crane will handle loads which average 50% of the rated
capacity with 5 to 10 lifts per hour, averaging 15 feet, not over 50% of the lifts at rated capacity.
Class D Heavy Service (CMAA Definition) - loads approaching 50% of the rated capacity will be handled
constantly during the working period. High speeds are desirable for this type of service with 10 to 20 lifts per
hour averaging 15 feet, not over 65% of the lifts at rated capacity.
