Our T type solid guide rail for elevator is a precision-engineered steel component designed for safe and stable movement of the elevator car and counterweight along the shaft. Its solid cross-section offers superior rigidity, reduced vibration, and enhanced safety in passenger and freight elevator applications. Manufactured in compliance with ISO7465 and ISO630 standards, our guide rails are machined to high tolerances for consistent performance.

Guide Rails —— Critical Components for the Installation and Operation of Elevators

To address the experience and concerns of owners and passengers, how the guide rails maintain low vibration and noise at high speeds?

First is to control the size accurately. After the guide rail materials is extruded into shape, it needs to be finished by CNC grinding machine or CNC planer, with the tolerance controlled within ±0.05 mm, to ensure the straightness and consistency of the cross-section shape of the guide rail in the full-length direction. Then, use the laser tracker or CMM to correct the relative position of the two guide rails to ensure that the parallel error between them is <0.1 mm/m and the vertical error is of the same level. In this way, when the car is traveling up and down at a high speed, the force is symmetrical, and the lateral runout caused by uneven rail clearance is reduced.

Next is surface preparation and lubrication. Based on phosphating or hot dip galvanizing, special low-friction electrophoretic coating or polytetrafluoroethylene (PTFE) micropowder coating is further applied to reduce the coefficient of kinetic friction between the wheel and the rail to below 0.1. Equipped with a lubrication system that automatically fills grease according to the number of times or hours of operation, and the type of grease is selected from high-viscosity anti-wear formulations to maintain the integrity of the oil film and avoid “dry friction noise” and micro-vibrations caused by direct metal contact.

Third, elastic guide shoe with vibration damping structure.  Traditional steel boots are prone to sharp noise and vibration during metal-to-metal sliding, while guide boots made of polyurethane or reinforced nylon absorb some of the impact energy through the material's own elasticity, attenuating high-frequency vibration and noise significantly. At the connection between the guide rail and the shaft wall, rubber gaskets or engineering plastic vibration damping blocks are added to disperse the vibration energy transferred to the shaft structure and avoid resonance amplification. 

Fourth, precise installation and dynamic adjustment. After the completion of the installation, the use of laser projector for three-dimensional alignment measurements, section by section fine-tuning bracket bolts, to ensure that the guide rail line shape in the entire shaft without obvious “bumpy” points. Installation of micro vibration sensors on the surface of the guide rail, together with the elevator operation data acquisition system, real-time monitoring of the vibration spectrum; once the trend of increase is found, the bracket can be adjusted or the guide shoe can be replaced in the next downtime maintenance.

Buffer & Brake Optimization. When the car reaches the top or the bottom, the flexible rubber buffer can effectively absorb the end impact energy and reduce the impulse vibration transmitted to the guideway by the “hard landing”. Adopting roller type or brake with soft cushion, it can decelerate by smooth friction when cutting off the drive, avoiding the double vibration of the instantaneous big impact on the guide rail and the car.

The low vibration and noise experience of riding the elevator not only enhances the owners' recognition of the project's quality but also reduces the maintenance costs caused by noise complaints. It is through the optimization of the whole process from material, processing, lubrication, vibration damping, installation to system coordination that the guideway can truly achieve a “senseless” level of smoothness and quietness when running at high speed.
