What is the problem with the friction sound and shaking of the elevator during operation：5 Common Problems
What is the problem with the friction sound and shaking of the elevator during operation?
The real reason What is the problem with the friction sound and shaking of the elevator
According to the situation you described, the elevator produces friction sounds and shaking during operation, which may involve issues across multiple mechanical and structural systems. Based on reference materials and industry experience, these symptoms can originate from guide rail misalignment, worn guide shoes, inadequate lubrication, or suspension system abnormalities. The following outlines the most likely causes along with corresponding inspection points and recommended corrective actions to ensure safe and stable operation.
1. Issues with the guide rail system
- Non-verticality or wear of the guide rail: Deviation in the verticality of the guide rail can cause uneven stress on the contact surface between the guide shoe and the guide rail, resulting in friction sound and car shaking
For example, for every 1 millimeter increase in the vertical deviation of the guide rail, the car shaking may increase threefold. - Excessive clearance between guide rail joints or dirt on the guide rail surface: Excessive clearance between guide rail joints (standard should be ≤ 0.5mm), or dirt on the guide rail may cause abnormal noise and shaking
2. Guide shoe component malfunction
- Wear or excessive clearance of the guide shoe liner: When the remaining thickness of the guide shoe liner is less than 1mm or the dynamic clearance exceeds 3mm, it is necessary to replace or adjust the spring preload force
- Dry friction between the guide shoe and the guide rail: If a sharp “hissing” sound is heard, it may be due to a lack of oil in the guide rail or severe wear of the guide shoe
3. Abnormal suspension system
- Uneven tension of the steel wire ropes can significantly affect elevator stability. When the force difference between individual ropes exceeds 5%, a calibrated tension meter should be used to measure and rebalance the loads to restore uniform traction.
- Traction wheel rope groove wear is a critical safety concern. If the bottom diameter wear exceeds 10% of the nominal diameter, the traction wheel must be replaced promptly to prevent slippage, abnormal vibration, and accelerated rope wear.
4. Loose or damaged mechanical components
- Loose fixing of car components: If the bolts of the gantry crane beam and car frame are not tightened to the standard torque (usually 28-32N · m), it may cause shaking
- Door wheel or bearing damage: When opening or closing the door, there is a “clunking” sound accompanied by the door jumping, which may be due to damage to the door wheel bearing or welding of the door wheel axle
5. Electrical system issues
- Poor contact in the brake circuit can prevent the brake from fully releasing, leading to resistance during start-up and resulting in noticeable shaking.
- Traction torque fluctuation caused by improper start-up torque settings—whether too low or too high—can disrupt smooth acceleration, producing jerks, vibration, and unstable car movement during initial operation.
—Suggested solution of the problem:
a. Stop and report immediately: Loud clanging noises or severe shaking may involve safety devices; stop operation and contact professionals at once.
b. Routine inspection: Check guide rail alignment, guide shoe liner wear, wire rope tension, traction wheel condition, and lubrication.
c. No self-repair: Only certified personnel should handle elevator faults.
Summary: The friction sounds and shaking experienced during elevator operation are commonly linked to issues with guide rails, guide shoes, suspension systems, or other critical mechanical components. Accurate diagnosis requires careful observation of the sound type, vibration frequency, and operating conditions. Because these faults can directly affect passenger safety and equipment integrity, safety must always come first. It is strongly recommended to stop operation if abnormalities persist and promptly contact certified elevator maintenance professionals for thorough inspection and corrective action.
