Maintenance and Failure Impact
1. Daily Maintenance Focus
Brake Shoe Wear Inspection: The gap between the brake shoe and the brake wheel needs to be adjusted regularly (usually 0.5~1mm). Excessive wear will lead to insufficient braking force and need to be replaced in time;
Spring Force Calibration: The spring tension must meet the design requirements. Insufficient tension will lead to a decrease in the brake force, and excessive tension may affect the life of the coil;
Coil Insulation Test: Prevent the coil from being damp or aging, causing a short circuit, causing the brake to be abnormally released or unable to be released.

The core role of the brake
Safety guardian: through mechanical spring force to achieve "power failure braking", to ensure that the elevator is absolutely stopped when stationary, faulty or in an emergency, it is the ultimate safety device to prevent the car from accidentally moving and falling;
Operation coordinator: cooperate with the motor control logic to achieve smooth start and precise braking, and improve riding comfort;
Key to standard compliance: Elevator safety standards in various countries (such as China GB 7588, EU EN 81 series) all require the reliability design of the brake, and its performance directly affects whether the elevator can pass the acceptance and annual inspection.
