This has a fixed supporting arm (1), on which a lifting arm (2), protruding outwards is guided, being raised and lowered by a hoist mechanism. The supporting arm can comprise two side beams (23) joined together, and in which the lifting arm is guided by means of rollers (21), while at the top it can have an anchoring lug and pulleys for a winch rope. There can also be a pulley on the lifting arm on a hinging component equipped with a locking bolt. This engages in one of the beams if rope tension slackens off.</p> |
