Modern pile vibrators basically work in the same way. Pairs of high-speed
contra-rotating eccentric weights are geared together so as to produce net
vertical vibratory forces.
The vibrations produced are transmitted to the pile through a powerful hydraulic

pile and much of the power generated is lost in shaking the ground.
The EMV is particularly effective for its size and weight because it is able to
utilise the crowd force available from the excavator to add further push force to
the pile.
The gearbox in the EMV unit is driven by a hydraulic drive motor that receives
hydraulic power from the excavators bucket ram circuit. Typically this circuit will

prevent excessive bearing loads and correct performance of the unit.
