Abstract
A vibratory exciter apparatus can be interchangeably connected to a variety of diverse vibratory compaction and other earth-working vibratory tools and includes a vibration-isolating connection link to tool carriers of varying sizes. A vibratory exciter housing is isolated from the connector link and from the carrying tool to which the link is attached by a primary elastomer isolator group which is, in turn, protected from damaging overload in a vertical downward direction by a secondary elastomeric isolator sheet and from damaging vertical load in an upward direction by a tertiary elastomeric isolator sheet. The connecting link utilizes adjustable bushing assemblies to accommodate dimensional differences from one boom manufacturer to another. The vibratory exciter unit includes heat-reducing shrouds for the rotary eccentric weights.
