Abstract

A load-carrying permanent magnet assembly having a plurality of permanent magnet units 2 suspended from a common frame 1, fluid operated release mechanisms 15 associated with respective magnet units, a piston and cylinder unit 3, 22 arranged between a lifting eye 20 and the frame and having its pressure chamber connected over conduits to the release mechanisms, an actuating member 8 operative through the fluid pressure system and suspension linkages to automatically anchor the piston cylinder unit to the frame in alternate lifting operations in such a way that the full lifting force applied to the lifting eye is developed across the piston cylinder unit; and a lever system 5 is mounted on the frame and mechanically connected between the piston cylinder unit and the lifting eye in such a manner as to apply only a fraction of the lifting force across the piston cylinder unit during the alternate lifting operations in which the piston cylinder unit is not anchored to the frame. <IMAGE>
