Field of Application

Bridge crane, gantry crane, tower crane, vehicle crane, crawler crane, port crane, etc.

Rotation-resistant design. The structure offsets the rotational torque by designing the opposite twist direction of the inner and outer rope strands, so that it can effectively prevent the load from spinning under the condition of single-rope lifting without a guide device, ensuring the safety and accuracy of the operation.

The outer layer is composed of 12 K7 compacted strands (7 strands of surface contact steel wire per strand) arranged closely, the middle layer is composed of 8 thin steel wire strands, and the inner layer is composed of 4 thick steel wire strands. Through the staggered layout of thick and thin strands and the alternating twist design (left twist on the outer layer/right twist on the middle layer), a triple anti-rotation torque balance is formed, and the rotation angle is reduced by more than 50% compared with ordinary 6-strand ropes.
