Structure for a secured access to the upper part of a transport vehicle

摘要

The structure (1) has two actuation devices (12, 14) fixed at a frame and a safety structure (10) by two articulated fixing units (18, 20), respectively. The safety structure is movable relative to the frame. The two actuation devices are spaced from each other according to a longitudinal direction of the safety structure. The two actuation devices vertically move the fixing units relative to the frame. A control unit independently controls the actuation devices to move the fixing units in opposite directions to tilt the safety structure in a vertical plane. The actuation devices are designed as screw jacks.
