Cushion

Cushions provide the necessary modification to the blow or impact created by a diesel, hydraulic, or air hammer.

There are 2 types of cushions: pile or hammer.

All cushions are consumables and will need to be replaced during driving operations. They become work hardened, destroyed by heat, or compressed beyond use and fail to provide the needed cushioning or dampening.
