Background

With the continuous development of economy in China, elevators are more and more common in the urban development in China, accompanying cables accompanying the elevators are diversified, and the elevator accompanying cables for video monitoring and the elevator accompanying cables for digital networks are provided. In the elevator movement, the cable is frequently bent and pulled, which affects the service life, and because various lines are too complex, the tensile property of the lines is relatively poor, and after frequent lifting movement for a long time, the lines are likely to be broken and damaged, which brings the consequences of power failure and stop or other related function interruption; this phenomenon is most likely to occur at the low-rise end of the trailing cable, which is most frequently used.

In order to ensure that the trailing cable has a sufficient service life, designers have to increase the diameters of various wires in the trailing cable or sacrifice part of the performance to improve the bending resistance of the wires, which not only increases the weight of the trailing cable, but also causes the trailing cable to consume more electric energy to bend the cable when moving along with the elevator.

Chinese utility model patent publication No. CNCN208477968U discloses a trailing cable for low-rise building elevator for this reason, include: the cable comprises a first input connector, a first output connector and a main cable, wherein the cross section of the main cable is circular or flat, and the main cable sequentially comprises a sheath layer, a braid layer, a control wire layer, a shielding layer, a main wire layer, a steel wire and a filler from outside to inside; the main cable is in the shape of an Archimedes spiral; the first input joint is arranged on the outer side of the disc-shaped main cable and fixed on the ground. This patent still adopts the steel wire as tractive spare for the retinue cable is still heavier.
