How to ensure the safe operation of elevators with steel wire ropes? The safe operation of elevators is a common concern of all sectors, and this is closely related to the steel wire ropes used in elevators. How to ensure the safe operation of elevators with steel wire ropes? Multiple different types of steel wire ropes work together, let's take a look together!

hoist rope

To ensure safety, each elevator will have multiple steel wire ropes for traction elevators, which are independently suspended from each other. From a structural perspective, a steel wire rope is composed of a core and strands - one or more layers of steel wire spiral twisted around the central steel wire to form a strand, and the strands spiral around the core to form a steel wire rope, which is rarely pulled apart.

In order to ensure the safety and stability of the traction ropes used in elevators, elevator inspectors also regularly inspect and maintain them. Once damage is found to the traction ropes, all elevator ropes need to be replaced to avoid uneven force distribution between new and old ropes due to differences in tension and elongation, and to improve the safety and reliability of elevators, Carrying people up and down safely.

Speed limiter rope

During the use of the elevator, the speed limiter can monitor and control the speed of the elevator car at any time. When the elevator speed reaches 115% of the rated speed of the elevator, the speed limiter will send a signal in a timely manner, blocking the wire rope used by the speed limiter, thereby driving the safety gear to act and locking the car on the guide rail, ensuring that the car will no longer fall or throw up.

When choosing the elevator steel wire rope for this type of speed limiter, usually 6 * 19 or 8 * 19 synthetic fiber core elevator steel wire ropes are selected.

Compensation rope

During the use of elevators, both the traction rope and the speed limiter rope will have weight, and if the weight of these extra steel wire ropes is not balanced properly, it may cause the elevator car to shake and make loud noise during operation, which not only greatly reduces the passenger experience, but also may cause safety accidents.

To avoid these situations, the setting of compensation ropes is also necessary in elevator steel wire ropes. Generally, 6 * 29F or 6 * 37M fiber core steel wire ropes are used.

Rope for door crane

Compared to the three types of steel wire ropes used in elevator cars, the main control of the door operator rope is the door operator system that directly faces passengers, and its actions are relatively frequent throughout the entire elevator system.

In order to ensure the safety and stability of the use of the door machine, galvanized steel core wire ropes of 6 * 7 or 6 * 19M types are generally used for the elevator wire ropes on the door machine.

How to ensure the safe operation of elevators with steel wire ropes? The safe operation of elevators is the result of the combined action of various types of steel wire ropes, speed limiters, and other safety devices, which need to be checked during maintenance.
