ABSTRACT:
In heavy mobile construction machinery such as backhoes, power shovels and boom cranes, wherein hydraulically actuated outriggers are extended for lateral stabilization, an automatically self-locking and self-releasing latching mechanism is provided to restrain an outrigger in its retracted inoperative position when not in use. The latching mechanism is operable in response to simple hydraulic actuation of the outrigger, and does not require manual operation or remote controls to effect locking or release of the mechanism.
