ABSTRACT:
A lifting device, for moving a pick-up arm upwards and downwards, has a lift rod guided by a guide element formed integrally with the deck plate. The lift rod has a pair of adjoining planar walls intersecting each other at an angle, and engaging a corresponding pair of guide walls of the guide element. A highly viscous damping material is arranged between these engaging walls. An oblique compression spring presses the lift rod downward and sideways into engagement with the guide walls, the spring force being directed in a plane which bisects the angle formed by the lift rod walls.
