<p>The cable guide mechanism includes rotary guide pulleys, e.g. for a top hoist cable, main hoist cable and auxiliary hoist cable. The cables lead from a fixed point to a point rotating w.r.t. the hoist or winch. Hoist cables guide mechanism includes a top hoist (1), auxiliary hoist (2) and main hoist (3) which stretches to the centre of rotary member (4), which in turn is connected with the crane or hoist mast. The main hoist is centred by plastics guide pulleys (5). To compensate for reciprocating cables movement along drum (8) a guide (7) is fitted. Guide pulley discs (12,13) which are pref. made of a plastics have rims of unequal height to improve cable guidance.</p> |
