Abstract: An optical scanning system for measuring and/or controlling a vehicle and/or parts of a vehicle, wherein the vehicle is arranged on a support surface. The optical scanning system comprises two optical reader apparatuses, which are arranged on said support surface, on opposite sides of the vehicle, and are provided with respective optical image capturing devices configured to provide respective data/signals encoding one or more images of the vehicle, an electronic system, which is designed to process the data/signals in order to construct one or more three-dimensional images of the vehicle. The optical image reader apparatuses each comprise a calibration target, which lies on an approximately horizontal support surface and is arranged immediately adjacent to the optical image capturing device of the relative optical image reader apparatus at a predetermined distance from it.

Abstract: A vehicle lift comprising a movement system configured to be installed in a pit in the ground, a platform engaged with the movement system and movable entering to and exiting from the pit, at least one arm carried by the platform and configured for contacting a vehicle to be lifted. The arm is movable between an extended position and a retracted position. The lift comprises a stop movable relative to the platform between a grip position where it engages the arm and a release position where it disengages the arm. The lift comprises an actuator carried by the platform and active on the stop to move said stop between the grip position and the release position.

Abstract: A vehicle lift comprising a column, a carriage slidably movable along the column, a movement system associated with the at least one column and configured to displace the carriage along the column. The movement system comprises an electric motor configured to drive in rotation a rotary member having a plurality of blades configured to generate an airflow during the rotation of the rotary member.

Abstract: A locking device for a maintenance machine such as a balancing machine, of a rotating body (5), having a fixed portion comprising a hollow fixed support element (2) borne by the maintenance machine, and a control system (59), and a movable portion comprising a bell-shaped member (12) with flange (13) mounted for rotation coaxial to said hollow support element (2) and designed to support the rotating body (5), and holding or locking means (68) arranged to removably fix the rotating body (5) against said flange (13) of the bell-shaped member (12), driving means suitable for driving, upon control, said movable portion in rotation.
