[0002] Elevator flat traveling cable is a vital component of the elevator system, which mainly connects the elevator car and the elevator machine room. Elevator flat traveling cable is a cable specially designed for elevator systems. Its flat shape makes it easy to move in the elevator shaft while maintaining stable signal transmission. It transmits the elevator's running speed, car position, door control signals and safety signals to the elevator machine room through the elevator control system.

[0003] The existing elevator flat traveling cables may break or be damaged after long-term and frequent lifting and lowering movements, resulting in power outages, suspension of operation or other related function interruptions.

The wire core assembly is installed in the flat outer sheath. The left and right sides of the flat outer sheath are arranged in arcs. The upper and lower ends are provided with two groups of triangular grooves arranged opposite to each other, which divide the inside of the flat outer sheath into three installation parts. The wire core assembly is provided with three groups, which are respectively installed in the three installation parts. The three groups of wire core assemblies are the first, second and third wire core assemblies. It increases its own load capacity and the required tension. When used in long-length suspension, it uses high-strength annealed soft copper wire bundles to extend the service life, high tensile strength, and reduce line loss.

[0005] In response to the above problems, although the solution given by the existing patent increases the load-bearing capacity and the required tension to improve the tensile and flexural strength, the cable is very likely to be scratched and worn after long-term use.
