Definition of elevator guide shoe

The guide shoe is a nylon block that can slide between the elevator guide rail and the car, called the guide shoe. It can fix the car on the guide rail so that the car can only move up and down. The upper part of the guide shoe also has an oil cup to reduce the friction between the shoe lining and the guide rail. Each elevator car is equipped with four sets of guide shoes, which are respectively installed on both sides of the upper beam and under the safety clamp seat at the bottom of the car; four sets of counterweight guide shoes are installed at the bottom and upper part of the counterweight beam. The guide shoes fixed on the car can move up and down along the fixed guide rail installed on the wall of the building shaft to prevent the car from tilting or swinging during operation.

The concept of comb plate

The comb plate is located at the running step or pedal entrance and exit, and is engaged with the step or pedal for the convenience of passengers. It is also a safety protection device for the elevator. There is a micro switch behind the comb plate. If a foreign object is stuck, the elevator can stop running. One side of the comb plate is supported on the front edge plate, and the other side serves as the fixed surface of the comb. Its horizontal inclination angle is <10 °. The structure of the comb plate shall be adjustable to ensure that the engagement depth of the comb teeth is ≥ 6mm.
