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 flange may not
be strong enough to support the girder weight. These
girders must be reinforced at the point where the beam
clamp engages the flange. 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
firmly 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.
