Clamp Inspection, Maintenance and Repair

It is important to establish a regular procedure for clamp
inspection. Campbell clamps are built to withstand rough
treatment. The clamp body and its components should be
free of grit, dirt, sludge and mud. Frequency of inspection
will depend upon the amount of use the clamp receives,
and may vary from one department or area to another. The
current revision of ASME B30.20, Below-the Hook Lifting
Devices, the national standard for plate lifting clamps,
details the inspection, testing, and maintenance of clamps
in its Structural and Mechanical Lifting Devices Chapter.
Please refer to this chapter for the frequency and details of
inspection not included below. The cam, pad and overall
condition of a Campbell clamp should be inspected by the
operator at every lift. More detailed inspections should be
made by a person familiar with the requirements of stan-
dard ASME B30.20 periodically with the interval dependent
on the use of the clamp. Detailed inspections should be
recorded to provide the basis for continuing evaluation of
the clamp. A sample inspection form is shown below.
Inspection Procedure
Cams and Pads: These are the parts likely to receive
most wear. Replace the cam and pad if the crown of any
one (1) tooth is worn or chipped more than 50% along its
length.
