ABSTRACT:
An improved vehicle-mounted lifting apparatus for a vibratory device. The apparatus includes bearings in which a principal pivot shaft is journaled, a lifting link and at least one center-bonded joint spaced along and nonrotatably mounted on the pivot shaft, a lift cylinder secured to the vehicle and extending to the lifting link, and a rigid arm extending from each center-bonded joint to a support for the vibratory device. Although a compact simplified lifting structure, excellent vibratory isolation to protect the lift cylinder is provided.
