Compensating Cables Roller Guidance System For High Speed Applications
The Weight Compensating Cable QuietLink II
Coated with PVC, the QuietLink II Cable serves to compensate for the weight of the traction ropes while the car moves up and down the shaft.
The QuietLink II Cable has proven itself as a truly quiet compensating product with a larger and more uniform loop than bare chains or chains with a sash cord.
Construction
Cable – Low carbon, welded proof coil chain Jacket – A high-quality polyvinyl chloride (PVC) adds mass and forms a round cross-section.
Application
This round filled configuration is designed for use at speeds of up to 3.5m/s.
Roller Guidance System for High Speed Applications
For elevator speeds over 350 ft/min and up to 490 ft/min (1.75 m/sec to 3.5 m/sec), a roller guidance system must be used with QuietLink II to dampen cable oscillations and prevent the cable from swaying. These rollers also help to maintain the natural loop of the compensating cable.
Purpose
The purpose of the guide rollers is to maintain the loop diameter and prevent any swaying of the compensating cable during stops and starts. The polyurethane also helps to dampen any vibration which may be caused by sudden stops and starts or air movement in the elevator shaft.
Each installation hardware kit includes: 3 U-Bolt (includes nuts, and washers), 1 shackle, 1 heavy duty grip for safe and economical installation of Quitelink II compensating cable.
Installation Advice
This diagram shows the approximate placement of components for a Quietlink II cable installation.

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.
