ABSTRACT:
A device and method for automatically vibrating the working members of a power construction vehicle such as a power excavator is disclosed. The device and method effectively change both the amplitude of vibration and the number of vibrations of a working member in proportion to a levering angle of an associated control lever during an excavating, breaking or ground hardening operation of a construction vehicle. The automatic vibration device is thus free from any select switch. The device simplifies the construction of the hydraulic system and more easily controls the automatic vibration operations, and thereby is convenient to operators.
