<p>The lifting gear is for mounting wall fitted water heaters. It has a trolley (1) on swivelling wheels (3), a vertical support (5) and a cable (17) winch (19). A slide moves inside the vertical support and has grips (15,16) for a support cradle (21,22). The vertical, movable, cradle rods (23,24) have, at their upper and lower ends, a shoe (25,26) with a pivoting contact, sliding and held by a spring. The slide grips can also be used with other handling tools such as spades or forks. An adjusting screw allows modification of the vertical support angle.</p> |
