摘要

The equipment is composed of an adjustable vertical fixed support formed from two tubes, the upper (2) sliding in the lower (1). A nut (3) fixes it at the desired height. A mobile lifting mast (9) and remote holding arm (8) effect lateral movements around the support which comprises two rotating collars (6,7). A chain (11) holds the mast and arm assembly separated from each other at their lower end. The arm is connected at the other end by a hinge (16). The mast has a coupling hook (13) in its upper end which receives lifting equipment (14) which extracts the shutter from its hinges by means of a fixing system (10) held by two steel clamps (12).
