Wire Ropes with Steel Core/Mixed Core(IWRC/IWRF) 9x17S+IWRC

Elevator wire ropes are critical load-bearing components that provide safe and reliable vertical transportation in traction elevator systems. These high-strength steel cables consist of multiple strands wound helically around a core, typically constructed from high-carbon steel for optimal durability and flexibility. Modern elevator ropes employ advanced designs like 8×19 Seale or Warrington configurations, balancing tensile strength with bend resistance to withstand repeated pulley movements.

Key specifications include diameter (ranging from 8mm to 16mm), tensile grade (usually 1570MPa or 1770MPa), and lubricant-impregnated fiber cores that reduce internal friction. Safety factors exceed 12:1 relative to maximum loads, complying with international standards (ISO 4344, ASME A17.1). The ropes interact with the traction sheave through precise friction physics, where groove patterns and rope tension are carefully calibrated to prevent slippage.

Characteristics:Preformed, bright, right hand, regular lay
Application:Suspension ropes for elevator speed ≥4m/s, building height ＞100m. Suspension ropes for high-rise, high-speed elevators

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
