Abstract:
A hydraulically operated wedge lock system provides a releasable mechanical lock between telescoping boom segments. Each wedge lock mechanism includes a stationary backing wedge block that defines an angled smooth surface. A stationary shaft and piston is supported generally parallel to the backing wedge block. A slidable wedge block biased by a spring to a locked position is supported for reciprocal movement on the shaft along the angled smooth surface. Hydraulic fluid urges the slidable wedge block against the bias of the spring to an unlocked position.
