    摘要: A shock absorbing apparatus (suppressor) for a vibratory pile driver includes three suppressor sections, including a first section adapted and arranged to absorb a load up to a selected amount. A second suppressor section is adapted to absorb a load above the first shock-absorbing section, with a third suppressor system providing a transition between first and second suppressor action as load increases.
