Best Practices- Changing Cushion

Due to the repetitiveness of impact, cushions can become worn down, charred or burnt overtime. Frequent checks on the cushion material is advised. For hammer cushions improper maintenance, thickness, or size of cushion material may result in damage to the hammer, including danger to crew and immediate area surrounding hammer due to falling hammer pieces. For pile cushions, many specifications call for a new cushion for each pile driven. If not changed for every pile, operator should be aware of condition of each pile cushion before driving.
