INTRODUCTION
Crosby CLAMP-CO beam clamps are below the hook lifting devices designed to provide
an efficient method for handling wide ange beam sections and plate girders. Always
follow the stated limitations discussed in this manual and shown on the product’s Warning
and Operating Procedure Labels.
Crosby Clamp-Co beam clamps have been safely and successfully used in the eld for
over 30 years. Your safe use of our products depends on you. Please be responsible and
make sure all people using our products follow these simple rules:
1. Beam Clamps are used to the purpose for which they were designed.
2. They are not loaded beyond their Working Load Limit.
3. They are properly lubricated and maintained.
4. They are inspected regularly and tested in accordance with the relevant statutory
regulations.
5. They are used by competent persons trained in their use.
6. Beam Clamps are returned to the factory every two years for inspection,
retesting and recertication.
As with all mechanical handling equipment, there is a degree of hazard involved with the
use of these beam clamps if not properly used. Failure to follow the appropriate safety
precautions and operating instructions may cause the load to slip or fall, and may result in
serious injury, death, or property damage.
GENERAL INFORMATION
Each Crosby Clamp-Co beam clamp is proof tested and certied prior to shipping. Beam
Clamps are proof tested to 200% of Working Load Limit.
Follow all requirements of laws, rules, and regulations applicable in your country pertaining
to lifting operations, ensuring all maintenance, testing, inspection and operator training
requirements are strictly adhered to.

PRODUCT WARNINGS
OPERATING PROCEDURES
• Perform regular DAILY inspections as recommended.
• Make sure clamp is centered on beam and tongs are totally engaged.
• Always use the tong restraining chains. Make sure the tong restraining chains are
engaged as tight as possible, and the free end is hooked back into the chain.
• Make sure the load and/or beam clamp does not strike anything during the lift.
• Use clamp for vertical lifting only, do not use in side loading applications.
• If two clamps are used to lift a beam, a spreader bar is recommended. Reference
page 6 for additional information.
• Temperature and environment: The temperature at which the standard lifting clamps
may be used lies between 212 F° (100 C°) and -40 F° (-40 C°). For other
temperatures and for use in hazardous environmental conditions, consult The Crosby
Group technicians.
WARNING
• Loads may disengage from clamp if proper procedures are not followed.
• A falling load may cause serious injury or death.
• The clamp shall not be loaded in excess of its rated load or handle any load
for which it is not designed.
• Never operate a damaged or malfunctioning clamp, or a clamp with missing
parts.
• Clamp not to be used for personnel hoisting.
• Do not carry a load over people.
• Do not leave suspended loads unattended.
• Operator and other personnel shall stay clear of the load.
• Do not lift loads higher than necessary.
• Do not make alterations or modications to clamp.
• Do not remove or obscure warning or operating procedure labels.
• See ANSI/ASME B-30.20 BELOW-THE-HOOK LIFTING DEVICES for additional
information.
• Read, understand, and follow these instructions and the product safety
information.

USING THE BEAM CLAMP
The beam clamp is designed to engage the beam anges when the clamp is lowered on
the beam. Make sure the clamp is centered on the beam and tongs are fully engaged.
When the clamp is in place on the beam ange, the restraining chains are put into place as
illustrated in Figure 4. It is important that these chains are in place when the beam is lifted.
If the beam or clamp accidentally impacts an adjacent structure, the chains will help to hold
the clamp tongs in place on the beam ange.
Do not attempt to repair a damaged clamp by welding or with unauthorized replacement
parts. We recommend returning the clamp to the manufacturer when repairs are required.
Slowly lower the clamp onto the beam and
center the clamp in-line with the beam’s
center of gravity (lengthwise) (See Figure 1).
Use the handle to pull the tongs out, if
necessary, and guide tongs under the
beam ange (See Figure 2).
Make adjustments until the tongs are rmly
gripping the beam ange and the clamp
is in center with the beam (See Figure 3).
Make certain the base plate is ush with
the top of the beam ange. Position the
restraining chains into place and ensure
they are secured with “S” hook. The clamp
is now secure for lifting (See Figure 4).
To remove clamp, descend until the clamp
is free of load. Disengage chain and place
“S” hooks end of chain on the keeper
hooks. Pull the tongs away from the anges
and lift the clamp free from the beam
(See Figure 5).

USING THE BEAM CLAMP
Do not attempt to make a lift with an unbalanced load. If
the beam or girder does not assume a level position, the
lift should be stopped and the beam clamp moved to the
balance point of the beam.
With some heavy girders, the top plate or ange may not
be strong enough to support the girder weight. These
girders must be reinforced at the point where the beam
clamp engages the ange. The project engineer should be
consulted to determine if this type of reinforcement is
required.
When two beam clamps are needed to lift a very long or
heavy girder, a spreader bar is recommended. If a double
leg sling is used in place of a spreader bar, it must be long
enough to insure a minimum horizontal angle of 75
degrees between each sling and the top of the girder.
INSPECTION AND MAINTENANCE
A visual inspection for cracks, wear, gouges and deformation as part of a comprehensive
documented inspection program should be conducted by trained personnel in compliance
with the schedule in ANSI B30.20. Proper maintenance of the beam clamp includes a daily
inspection and weekly lubrication. There are labels attached to the clamp frame which
provide required maintenance, inspection and lubrication recommendations. Product
labels should be replaced when they are no longer legible. Contact The Crosby Group for
replacement labels.
• Inspect pin welds for cracks or signs of failure. (1)
• Inspect all load carrying welds for cracks or signs of failure. (2)
• Inspect non-skid points. Points should not be deformed or worn off. Points should be
rmly in place. (3)
• Lubricate all pins and moving parts with oil can or spray at least once a week. (4)
INSPECTION AND LUBRICATION POINTS
Do not attempt to repair a damaged clamp
by welding or with unauthorized
replacement parts. We recommend
returning the clamp to the manufacturer
when repairs are required.

INSPECTION AND MAINTENANCE CHECK LIST
• Is any part of the equipment distorted?
• Are any cracks visible, or is extensive corrosion evident?
• Is there wear evident at suspension points, shackles, master link, pivots, pins, bolts,
threads, or other moving and/or load bearing parts?
• Is restraining chain and grab hook locking arrangement functional?
• Are the Working Load Limit, Serial Numbers and Warning labels legible?
• Have all inspections and maintenance been regularly recorded?
• Does the Crosby Clamp-Co product carry its original Identication Plate and Warning
information?
• If the identication plate has been damaged or removed, the clamp shall be taken out
of service and arrangements made to replace the identication plate.

BEAM CLAMP MODELS
There our several Crosby Clamp-CO beam clamp models. They are designed for use with
beams of different weights and ange dimensions. See list of models on this page. It is
important that the correct clamp model is used for each beam size and weight that is lifted.
Each clamp should have an identication plate which shows the clamp model, the
maximum Working Load Limit (WLL), and the minimum and maximum ange dimension
the clamp is authorized to lift.
The clamp model must be selected to t the ange dimensions of the beam to be lifted.
Smaller or larger beam anges will not t properly, and will interfere with the clamping
action of the beam clamp. Never exceed the Working Load Limit (WLL) that is shown on
this page and also shown on the clamp’s identication plate. If the person using the clamp
is uncertain as to the beam’s weight and ange dimensions, the project engineer should be
consulted to obtain the correct information.
