WebThe flexibility of the wire rope is an important consideration where sheaves are small or where the rope makes many bends. Flexibility in wire ropes is achieved by using a large number of small-diameter wires. The wire rope of 6 × 7 construction consists of a few wires of relatively large size. It is too stiff for hoisting purposes. WebChoose from our selection of rope sheaves, including over 350 products in a wide range of styles and sizes. In stock and ready to ship.
