Abstract

A crane apparatus includes an upstanding mainframe and a boom unit supported for pivoting movement on the mainframe about a horizontal axis. The boom unit includes a base boom, an outer boom section of one or more outer booms, and a fluid-actuated piston-and-cylinder assembly. A pair of space mounting walls are presented by the base boom in which a hole is defined, and the piston-and-cylinder assembly includes a proximal transverse sleeve sized for receipt between the spaced walls of the base boom in alignment with the hole. A pin is provided that is sized for receipt in the hole and the tubular sleeve for securing the piston-and-cylinder assembly to the base boom. Removal of the pin enables the outer boom section and piston-and-cylinder assembly to be removed from the base boom.
