ABSTRACT:
The digging chain support boom of a continuous chain type excavating machine is vibrated in a directional mode so as to enhance digging efficiency. Directionally compliant mounting of the boom isolates this vibration from the machine proper while allowing unimpaired application of digging torque and crowd forces.
