Elevator Safety Gear Fault Symptoms Analysis
Among all elevator safety protection devices, the safety gear is widely recognized as the final physical line of defense against car overspeed or free fall. Once the overspeed governor is activated, the safety gear must immediately grip the guide rails and forcibly stop the car.
However, during long-term maintenance and inspection, hidden safety gear faults are often overlooked. This article provides an in-depth analysis of common safety gear failure symptoms and recommends high-quality spare part solutions from the globally recognized elevator parts supplier A-FLY.
1. Warning Signs: Typical Symptoms of Elevator Safety Gear Failure
The performance of the safety gear is directly related to passenger safety. If your elevator exhibits any of the following conditions, immediate shutdown and inspection are strongly recommended:
Abnormal Friction Noise During Operation
When the clearance between the safety wedges and the guide rail is incorrectly adjusted, the wedges may slightly contact the rail even during normal operation, producing continuous metal scraping noises or abnormal sounds.
Linkage Mechanism Jamming
Due to insufficient lubrication or corrosion caused by humid environments, the safety gear lifting linkage may become stiff or fail to return smoothly. This can prevent the safety gear from engaging promptly in an emergency.
Uneven Braking Force on Both Sides
If the wedge blocks on the left and right sides wear unevenly, braking force will be inconsistent, potentially causing the car to tilt and permanently damage the guide rails.
Difficulty in Resetting After Activation
If the wedge blocks cannot be released smoothly during reset, it usually indicates internal spring fatigue or mechanical structure damage.
2. Essential Elevator Spare Parts for Replacement and Maintenance
Reliable safety gear performance depends on high-quality elevator spare parts. During modernization projects or routine maintenance, the following components are critical:
High-Performance Wedges / Clamping Blocks
These components make direct contact with the guide rails and must have exceptional hardness and wear resistance.
Linkage Rod Assemblies
They ensure synchronized actuation and reduce the risk of delayed response caused by mechanical lag.
Disc Springs and Reset Springs
These provide stable initial pressure and ensure accurate reset after safety gear activation.
Overspeed Governor Rope Accessories
Since safety gear activation relies on the overspeed governor, related components such as rope clamps and tension sheaves must also be carefully inspected.
