Abstract
A crane vehicle is provided with a carrier and a rotating deck pivotable around a vertical axis thereon on which a boom swivellable around a horizontal axis is supported. Pallets are mounted at the projecting outer end of the rotating desk at both sides to receive counterweight slabs stacked on top of one another. To produce a greater balancing counter-moment to the boom and the load suspended thereon without putting on additional counterweight slabs, a frame can be attached to the outer end of the rotating deck, said frame being provided with accommodations or couplings at least for the respective rear suspension points of the pallets.

A crane vehicle having a carrier and a rotating deck (1) pivotal around a vertical axis (2) thereon and on which a boom swivellable around a horizontal axis is supported,
- outer end pallets (6, 7) mounted at both sides of the rotating deck (1) and structured and arranged to each receive counterweight slabs (8) stacked on top of one another, and
- a frame (14) removably attachable directly to an outer radial end of said rotating deck (1) projecting away from said vertical axis (2),
- said frame (14) being provided with counter-accommodations or couplings (16) at least for respective rear suspension points (11) of said pallets (6, 7) with respect to said vertical axis (2), and
- said pallets (6,7) each structured and arranged to be attached to said frame (14) on opposite sides from one another and circumferentially with respect to rotation of said deck (1) about said vertical axis (2).
