Abstract
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.
Claims9
A shock-absorbing apparatus for use with a pile driving and/or pile pulling vibratory device and a carrying member for supporting the vibratory device, the shock-absorbing system comprising:
- a base portion adapted for connection to the vibratory device;
- an outer housing section supported by a carrying member, wherein tension loads are applied to the carrying member;
- a first shock-absorbing assembly connected between the housing and the base portion for absorbing the vibratory action or force generated by the vibratory device for a selected range of tension load as the outer housing is raised;
- a second shock-absorbing assembly for absorbing the vibratory action or force generated by the vibratory device for a load greater than the selected range of tension load;
- a third shock-absorbing assembly operative to absorb vibratory action or force generated by the vibration device, arranged to produce a transition between the first and second tension loads and operation of the first and second shock absorbing assemblies;
- and
- a stop element for limiting relative movement of the connecting elements in the event of a partial or complete breakdown of the first, second and third shock-absorbing assemblies.
