Multi-stage suppressor for vibrating pile driver

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 apparatus 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, comprising a first set of elastomeric members, connected between the outer housing section and the base portion for absorbing the vibratory action or force generated by the vibratory device for a first tension load with a selected range as the outer housing section is raised;
• a second shock-absorbing assembly, comprising a second plurality of elastomeric members, for absorbing the vibratory action or force generated by the vibratory device for an additional tension load greater than the selected range of tension load as the outer housing section continues to be raised;
• and
• a third shock-absorbing assembly, comprising a third plurality of elastomeric members, separate from the second shock-absorbing assembly, operative to begin absorbing vibratory action or force generated by the vibration device for the additional tension load following initial operation of the second shock absorbing assembly, providing a shock absorbing transition between the first and additional tension loads and operation of the first and second shock absorbing assemblies.
