Abstract
A mobile crane includes a boom extension assembly carried alongside a telescoping boom assembly in a stowed position. The boom extension assembly includes a fly section with a first portion adapted for being connected to the head end of the boom assembly in an operative position while a second portion of the fly section adapted for being connected to the first portion remains in the stowed position. The first portion of the fly section may: (1) be shorter in length than the corresponding second portion of the fly section; (2) include sheaves for supporting a hoist line; (3) include a tapered end; or (4) be used in combination with two additional sections of the boom extension assembly. A related method includes connecting a first, shorter portion of a fly section to a head end of a telescoping boom assembly while a second portion remains in a stowed position.
