ABSTRACT:
In heavy mobil construction machinery such as backhoes, power shovels and boom cranes, wherein outriggers are extended for lateral stabilization, an automatically self-locking and self-releasing mechanism is provided to restrain an outrigger in its retracted inoperative position when not in use. The 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.
