Abstract: Self-propelled carriage on wheels includes: one or two pairs of supporting elements for the wheels of either or both of the axles of the motor vehicle, these elements being movable symmetrically and perpendicularly with respect to the longitudinal axis of the carriage and designed to center, immobilize and lift from beneath the wheels; elements for limiting the mass to be transferred; elements for sensing, continuously during the transfer, the translational position of the carriage; elements for sensing the presence of the motor vehicle on the carriage and measuring the front and rear lengths of the motor vehicle relative to its front axle; and elements for sensing excessive displacement of the longitudinal axis of the motor vehicle relative to the longitudinal axis of the carriage when the motor vehicle is being positioned by the user in the entrance bay.

Abstract: A vehicle parking apparatus comprises at least one lift platform (12) which can be brought to parking boxes (11) provided in rows in different stories of a multi-story car park and on which at least one movable vehicle carrying pallet (13) can be arranged. The vehicle carrying pallet is formed by two box-like wheel supporting beams (14) which extend in the direction of travel and which have a length corresponding to the wheel base of the vehicle types to be accommodated and also a lateral spacing corresponding to the track widths of the vehicles to be accommodated. The wheel supporting beams (14) are in the form of an inverse U with outwardly directed angled portions (15) at the lower longitudinal edges and plates (16) which connect the lower longitudinal edges together as well as longitudinal roller arrangements (17) at the front and rear ends. At least one cross-beam (18, 19, 20) is provided at the front and at the rear of the wheel supporting beams.
