What impact source is used in pile driving hammers?

The leads section guides the pile hammer and drive cap. The lifting gear supports the leads section and provides spacing for the ram and has a starting line if a diesel hammer is used. The pile guide aligns the leads, hammer and drive cap with the pile.
What is a pile follower?
A follower is an extension between the pile head and the hammer that transfers the blow to the pile in which the pile head cannot be reached by the hammer or is under water . For construction of driven piles, the piling frame and hammer are normally erected on existing ground level but not at the base of pile caps.
