Abstract
The utility model discloses an alternate lay wire rope for sand dredger hoisting equipment. The alternate lay wire rope comprises a rope core formed by a jute rope; six outer layer strands are disposed around the rope core; and the lay pitch multiple of the wire rope is 6.0 to 6.8. Through adjustment of a strand structure and reduction of the diameter of steel wires of the outer layer strands, the alternate lay wire rope has improved physical performance and mechanical performance, solves the problems of wire and strand breakage caused by serious abrasion between the steel wires and easy fatigability and poor toughness of the steel wires because of greater diameter of the steel wires in the outer layers strands of a conventional wire rope, and has improved overall rope breaking force. The design that each steel wire is disposed on the peak base of an adjacent steel wire of a lower layer guarantees stability of the positions of the steel wires and reasonable structure, improves the overall rope breaking force of the wire rope by 8%, and prolongs the service lifetime of the wire rope.
