Abstract:
An outrigger assembly for stabilizing a mobile work machine, comprising:a stationary support housing mountable to the work machine; an inner housing telescopically positioned within the support housing; a first drive cylinder operatively positioned between the support housing and the inner housing, the first drive cylinder being operable to move the inner housing between a retracted position in which the inner housing is positioned within the support housing and an extended position in which the inner housing extends from the support housing; a leg assembly telescopingly positioned within the inner housing; a second drive cylinder operatively positioned between the leg assembly and the inner housing, the second drive cylinder being operable to move the leg assembly between a retracted position in which the leg assembly is contained within the inner housing and an extended position in which the leg assembly extends out of the inner housing; and a pivot cylinder operatively connected to the leg assembly to pivot the leg assembly between the extended position and a ground engaging position; wherein the first drive cylinder, the second drive cylinder and the pivot cylinder are independently operable such that the leg assembly can be moved to the extended position and the leg assembly can be moved to the ground-engaging position while the inner housing is in the retracted position.
