To achieve the above object, the utility model provides following technical scheme：Engineering machinery luffing specialized wire rope, including Steel wire rope body, the steel wire rope body include first layer rope strand, second layer rope strand body and steel wire rope body stock core, and Two layers of rope strand body outsourcing, which are twisted with the fingers, first layer rope strand, and the intrinsic second layer rope strand bag of second layer rope strand is twisted with the fingers in steel wire rope body stock The outside of core, the first layer rope strand are disposed with first layer rope strand stock core, first layer rope strand compound steel silk, from inside to outside One layer of rope strand, two layers of steel wire and first layer rope strand layer of steel wire, the second layer rope strand layer of steel wire bag on the outside of the second layer rope strand Sth. made by twisting is filled out between the outside of second layer rope strand stock core, the steel wire rope body stock core and second layer rope strand filled with second layer rope strand Layer is filled, first layer strands fit layer is filled between first layer rope strand and the second layer rope strand body.

Preferably, the steel wire rope body stock core is twisted with the fingers by seven strands of steel wire bags and formed.

Preferably, the second layer strands fit layer and first layer strands fit layer are made by EPDM rubber grain material.

Preferably, the first layer rope strand layer of steel wire, two layers of steel wire of first layer rope strand, first layer rope strand compound steel silk and Second layer rope strand layer of steel wire is made by stainless steel component.

Preferably, the first layer rope strand is twisted with the fingers by 30 one steel wire bag and formed.

Compared with prior art, the beneficial effects of the utility model are：Compared with prior art, steel cable is most for the equipment Small rupture pull force value improves 15% ~ 20%, and shock resistance improves, the Stability Analysis of Structures of steel cable, and service life improves 2.5 ~ 3 times. Serve and save steel, save the energy, the low consumed effect of drop；The wire rope core of compacting stock composition forges through overall again after twisting, The twist direction of wire rope core and the twist direction of steel cable are on the contrary, to balance the moment of torsion of the inside and outside layer of steel cable；The utility model have steel wire strand bag twist with the fingers and Into intensity is higher, the rotation for the steel cable that can determine, beats torsion problem, improves the service life of steel cable.
