recently published an article on plate clamp inspection and operation based on a presentation given by one of Columbus McKinnon’s corporate trainers, Chris Zgoda, at the ACRP Conference in San Antonio, TX.  Below are a few of the highlights:

Plate Clamp Operation
Plate clamps are most often used to lift and move steel plates from both horizontal and vertical positions. CM’s clamps operate through a self-actuating spring that engages when the clamp is attached to a plate. When using plate clamps, it is important that the load is close to the clamp’s working load limit – weighing no less than 20 percent of the clamp’s working load limit.

Inspecting a Plate Clamp
Lifting clamps are just like any other piece of machinery and therefore require frequent inspection and maintenance. Clamps should be inspected every one to four weeks, depending on frequency of use. Plate clamps should be degreased and cleaned regularly and should be lubricated as needed to ensure smooth operation. When inspecting clamps it is important to check the teeth, handle, shell plates and other components like bolts, nuts and chain.
