Crane Operator Crushed Between Two Steel Frames When Rigging Failed
The operator of an overhead crane had been using a chain sling attached to the hook of the crane, and was setting it up into a single choker hitch to pick up and turn over the steel frame, that was lying horizontally on two sawhorses. The hook on the sling did not have a safety latch. The operator was standing between the load and another steel frame that was leaning vertically against the shop platform. The chain disconnected from the hook and the vertical steel frame fell towards him. He was crushed between the two steel frames. [Source: OSHA Case Histories – Rigging Accidents- Case History #7]

"Devil is in the Details"
The CrosbyIP IPSC10 screw style clamp is suitable for use in positioning and turning steel plates and sections. The
pivots (clamp pads) of screw clamps are usually small in size, but actually do all the hard work. When it comes to safety of life and load, CrosbyIP takes care of every little detail of their clamps. The pivots of CrosbyIP clamps undergo a proprietary hardening process, resulting in a strong, yet ductile core and an extremely high surface hardness. To make sure that the pivot keeps the specified hardness and strength, no further surface treatment is done, as this may induce unwanted reactions (such as hydrogen embrittlement).
So, whatever you are lifting or handling, choose CrosbyIP Lifting Clamps
