Abstract:
A removable outrigger unit is provided for a crane vehicle to provide weight reduction for over-the-road travel. Alignment cams allow rapid attachment/removal with respect to the vehicle frame. In a first or rear mounted embodiment, the outrigger has guide pins on spaced hangers that engage hooks on lugs mounted on the vehicle frame and rotary eccentric cams on the hangers that provide point alignment contact. A second or front mounted embodiment includes rotary eccentric and linear cams on the outrigger that contact side/bottom edge faces of cooperating dual lugs on the vehicle frame. The cams in both embodiments are preadjusted by bolts so that contact with the lugs occurs when corresponding lock pin receiving apertures are aligned. Double acting hydraulic cylinders on the outrigger move opposed lock pins through the aligned apertures and secure the outriggers to the frame. At least one support beam of the second embodiment includes pivotal beam extensions with an offset jacking cylinder.
