High-Speed Roller Guide YHCY-4
YHCY-4 is a high-speed roller guide designed for elevator car applications, with a rated speed of up to 5 m/s and a steel spring system.
The steel spring suspension system with optimized preload force keeps the cabin centered on the guide rail and balances the pressure applied by the rollers to the rail. The stopper mechanism developed by our company keeps the spring movement under control, damping vibration, noise, and sway effects that may occur at high speeds.

Advantages of the Steel Spring Suspension System
> Stable Guidance
The steel spring structure with optimized preload force balances the pressure applied by the rollers to the rail and ensures stable cabin guidance along the guide rail.
> Controlled Roller-Rail Contact
The spring system optimizes the pressure applied by the rollers to the rail, reducing roller wear and extending the service life of the guide rails.
> Long-Lasting Mechanical Memory
Our springs are made from high-quality steel suitable for both static and dynamic operation. They maintain their form even after repeated compression cycles, helping the elevator preserve its original ride comfort over many years.
> Instant Response to Variable Loads
Even when the load distribution inside the cabin changes, the spring mechanism absorbs these changes within milliseconds. Unlike fixed block systems, the system remains flexible and safe at all times.
> High-Speed Stability
At high speeds, loaded elevators may be affected by cabin load shifts, yawing moments, and guide rail joint impacts. Thanks to the specially calculated “k factor,” the system absorbs these forces before the spring reaches the stopper.
> Dynamic Centering
After high-precision adjustment of the steel springs, the preload force and maximum spring force are optimized. This allows the roller guide to keep the cabin centered on the rail at variable speeds and eliminate vibration at the source. As a result, passengers experience a more comfortable ride.
