Abstract
A lifting platform installed in a pit, especially for tracks, has at least two lifting devices. At least one of the lifting devices is movable in the longitudinal direction of the pit for adapting to the axle spacing of the vehicle to be lifted, and at least of one lifting devices has two laterally projecting wheel forks for holding the wheels of a vehicle axle. The lifting device with the laterally projecting wheel forks is combined with an axle lifter, which is allocated to the axle of the wheels in the wheel forks and which is vertically movable independently of the wheel forks.
Claims12
A lifting platform for vehicles, the lifting platform being installed in a pit (1) and comprising at least two lifting devices (2, 3), at least one of the lifting devices being movable in a longitudinal direction of the pit for adapting to axle spacing of a vehicle to be lifted, at least one of the lifting devices having two laterally projecting wheel forks (20a, 20b) for holding wheels of one vehicle axle, and an axle lifter (24) combined with at least one of the lifting devices having the laterally projecting wheel forks (20a, 20b), the axle lifter being allocated to the axle of the wheels held in the wheel forks (20a, 20b) and the axle lifter being vertically movable independently of the wheel forks, wherein at least one of the wheel forks includes a wheel support (31a, 32a, 31b, 32b) displaceable in a direction approximately parallel to the axle of the wheels, wherein the lifting devices (2, 3) are connected to a synchronizing controller, the controller being configured such that, for a raised vehicle, the controller permits lowering of only the wheel forks (20a, 20b) of one axle while simultaneously locking the axle lifter (24) corresponding to the one axle and locking the wheel forks (20a, 20b) corresponding to another axle.
A lifting platform for vehicles, the lifting platform being installed in a pit (1) and comprising at least two lifting devices (2, 3), at least one of the lifting devices being movable in a longitudinal direction of the pit for adapting to axle spacing of a vehicle to be lifted, at least one of the lifting devices having two laterally projecting wheel forks (20a, 20b) for holding wheels of one vehicle axle, and an axle lifter (24) combined with at least one of the lifting devices having the laterally projecting wheel forks (20a, 20b), the axle lifter being allocated to the axle of the wheels held in the wheel forks (20a, 20b) and the axle lifter being vertically movable independently of the wheel forks, wherein at least one of the wheel forks includes a wheel support (31a, 32a, 31b, 32b) displaceable in a direction approximately parallel to the axle of the wheels, and wherein the lifting devices (2, 3) are connected to a synchronizing controller, the controller being configured such that the wheel forks or the axle lifter of one lifting device (2) supporting weight of the vehicle can only be moved simultaneously and at an equal lifting speed and in a same direction as the wheel forks or axle lifter of another lifting device (3) supporting weight of the vehicle.
