Servo operated access step for utility vehicle - has underfloor ram linked to swing mounting by cable drive

摘要

The servo operated access step for a utility vehicle has a hydraulic servo ram mounted under the floor and linked to the pivotted step by a cable. The step is swung into the erected position by springs and is pulled by a lever operated by the ram. The steps are operated by a control linked to the door opening. The stroke of the ram is extended using a link lever with the cable on the free end of the lever. The cable is threaded over a roller under the door frame and the top step folds flat against the support frame as the bottom step is raised.
