Suspension for twin cable lifting grab - includes guide to keep cables apart and direct them along grab axis of symmetry

摘要

The grab suspension has a pulley block opening and closing mechanism worked by these cables. One suspension cable is connected to the block moving part and the end of the other is fixed to a fixed grab part. - The fixing of the suspension cable (17) to the block moving part (9) pivots around its support (20). There is a guide (21) for the other cable (18) to keep the cables apart. The guide also directs either cable along the axis of symmetry (15) of the grab (3) when held.(1/3)
