Pile hammers are a dedicated attachment for driving sheet piles into and pulling out of most ground conditions. Sheet piles are used to re-enforce banks or are put in as temporary structures to protect a workforce working below ground level.
There are 4 models of EMV available to suit different sizes of excavator and pile.
The pile hammer lifts the pile vertically using the built-in lifting chain; it is then tightly gripped in a powerful hydraulic jaw. Once secured, the pile is then vibrated using high frequency vibrations and the down-crowd force of the excavator boom (along with the self-weight of the pile) into the ground. This process works in reverse to extract piles.
