ABSTRACT:
A crane vehicle which reaches a minimum traveling speed of 62 km/h on public roads and gives the vehicle driver a range of vision with a radius of not more than 12 m comprises a vehicle frame which is substantially lowered to the level of the centers of the vehicle wheels, with at least part of the vehicle wheels being provided with hydrostatic individual wheel drives that are respectively arranged in the area of the wheel hubs. Furthermore, the crane vehicle comprises motor means for travel operation and crane operation, with said motor means being supported above the vehicle frame in a turntable which is supported on the vehicle frame in a horizontally pivotable manner. When viewed in the direction of travel, a driver's cab is mounted upstream of the motor means on the turntable, and a split longitudinal spindle which is mechanically lockable with the steering means for the vehicle wheels for travel operation is provided in the area of the driver's cab. The boom of the crane vehicle is adapted to be placed with its front end on the low-lying vehicle frame and has a basic boom length corresponding substantially to the length of the vehicle frame.
