A crane and an attachment comprising a counterweight support beam including a plurality of connected segments movable relative to each other, and having a fore end adapted to be connected to the crane upper works, and an aft end rearward from the rear portion of the upper works. The attachment also includes a moveable counterweight carrier adapted to carry a counterweight when the counterweight is supported thereon. The carrier is mounted on the support beam for movement along the length thereof. The attachment also includes a cylinder for selectively moving the counterweight carrier fore and aft along the beam, landing gear for normally supporting the aft end of the beam on the ground, and a backhitch pendant and a pendant cylinder interconnecting the aft end of the beam and the top of the mast for raising the landing gear from the ground incident to lifting a heavy load from the boom. The support beam is extendable by moving the connected segments relative to each other between a first position, wherein the aft end is spaced from the rear portion of the crane upper works, and a second position, wherein the aft end is spaced further from the rear portion of the crane upper works.
