ABSTRACT:
A variable reach rough terrain load lifting apparatus comprising a vehicle having a frame; a boom having innermost, intermediate and outermost telescoping boom segments; and means for pivotally connecting the outermost boom segment to the vehicle frame and capable of reciprocal longitudinal movement therewith. The outermost boom segment has first and second hydraulic cylinders mounted therein for extending and retracting the intermediate and innermost boom segments, respectively. The pivotal connection means facilitates pivotal movement of the boom with respect to the vehicle while preventing buildup of corrosion products which would interfere therewith and further to facilitate repair or replacement thereof due to normal operation. The innermost boom includes end effector means attached to the forward end thereof by means for quick connection and disconnection. A pair of outriggers are located on opposite sides of the front of the vehicle for providing upward stabilizing forces to the front end of the vehicle when the boom is extended at maximum loads.
