Abstract: A pantographic device for conveying loads in vehicle assembly lines includes a horizontal assembled drive shaft on an upper frame and with the capacity to rotate, several parallel pulleys fixed to a drive shaft, two motors acting on the opposing ends of the drive shaft providing its rotational movement, and several flat belts fixed to the pulleys of the drive shaft on one end and two a lower frame on the opposite end, so that the rotation of the drive shaft in one direction and the other determines vertical lifting and lowering of the lower frame with regard to the upper frame.

Abstract: This table comprises scissor arms (1, 2) assembled on a common rotation axis (3) and two thrust shafts (6, 7) shifting by the action of drive means and acting on the opposite sides of the scissor arms (1, 2), causing the tabletop (5) to lift or lower. The drive means comprise: a geared motor (8) providing a rotational movement to a first thrust shaft (6); an anti-rotation support (9) preventing the geared motor (8) from rotating around said first thrust shaft (6), and belts (10) fixed to the anti-rotation support (9) by one of their ends and to the periphery of the first thrust shaft (6) by the opposite end, wrapping around the second thrust shaft (7) with their intermediate area.

Abstract: A device for transporting vehicles during manufacturing is disclosed that allows for upward and downward movement of the vehicle but avoids adverse longitudinal or transverse swinging. The inventive device includes a moving carriage mounted on a fixed rail, an upper frame, a lower frame moveably connected with an elevation mechanism and at least one first pair of articulated arms for stabilizing the vertical movement of the vehicle. An additional pair of articulated arms may be provided which extend and retract in a plane that is perpendicular to the first pair of articulated arms. Additional stabilizing roller elements connected to a fixed rail are provided on a lateral arm of the upper frame to prevent swinging of the upper and the lower frames of the transporting device.
