Abstract
A crane including a telescoping boom has a base boom member and an inner member slidably mounted in the base boom member with a first end projecting from the base boom member. The inner member includes first and second connector elements. A boom extension has a first end including first and second attachment elements. The boom extension also includes first and second spaced bracket assemblies and is shiftable between use and storage positions. A first support associated with the base boom member includes a holder for pivotably retaining the first bracket assembly and a second support has a rail projecting from the base section. A slider is slidably supported by the rail, and an actuator connected between the slider and the boom shifts the slider between a retracted position and an extended position relative to the base boom member. A method of deploying a boom extension is also disclosed.
