Chain Clamp System in Use

Function

The chain clamp system consists of a locking clamp and a chain with a piece of wire mounted to the one end. For use the free end of the chain is mounted to a wire in a hoisting system – e.g. on a piling machine or directly to a vibratory hammer. The clamp body indexes along the links of the chain and locks into place giving a quick and stable chain lock for lifting.

Safety Latch

The chain clamps are available with or without a safety latch – please note the yellow part in the picture. The safety latch contributes to extra safety.

 

 

Operation

To lift a sheet pile, thread the wire and – of safety reasons – at least 6 chains links through the hole in the sheet pile and then through the opening in the locking clamp, while the spring operated trapping pin of the clamp is pressed in with a thumb. When the pressure is loosened the trapping pin assembly will automatically lock to the chain and hoisting can take place.

After hoisting the trapping pin is pushed in and the clamp removed from the chain.

When not in use the piling operator with advantage can have the clamp in his pocket.
