Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a reinforced elevator follower composite cable. Background Art

[0002] In the construction of modern buildings and high-rise buildings, lifts or elevators are widely used. With the development of lift technology, more and more functional equipment is carried in the elevator lifting platform or car, and the requirements for cable functions are also increasing. The number of follow-up cables that move with the elevator is also increasing, resulting in a large number of scattered cable harnesses with corresponding functions being dragged during the operation of the elevator, making the installation and laying of the equipment difficult. During the operation of the elevator, various cables are pulled, entangled, and repelled by each other in an unbalanced manner, causing the cables to be easily damaged, with a short service life and unpredictable failures. As a result, the elevator often has various functional failures. When repairing the corresponding faults, a large number of scattered harnesses bring great inconvenience to the maintenance work.
