The manufacturer of the elevator call board reminds passengers to pay attention to whether the elevator car is in the corresponding floor position before entering the elevator with the floor door open.

1、 There are several common faults and causes in mechanical systems, including the following categories

1. Due to poor lubrication or lubrication system failure, the rotating parts of the components may experience severe heating, wear, or shaft gripping, resulting in damage to the rolling or sliding parts of the components.

2. Due to frequent use of elevators, some components have worn out and aged, and maintenance is inadequate. Failure to replace or repair worn parts in a timely manner has further expanded the damage, forcing the elevator to shut down.

3. During the operation of the elevator, some fastening screws may loosen or come loose due to vibration, causing abnormal operation of certain components, especially moving parts, resulting in damage to the elevator.

4. Due to the imbalance of the elevator balance coefficient or severe overload, the elevator main board may cause significant shaking of the car or poor leveling accuracy, leading to uncontrolled elevator speed and even causing the top or bottom of the pier to collide with the speed limiter safety clamp, causing the elevator to stop.

2、 Generally speaking, if the fuse in a local circuit frequently burns out, it indicates that the component or wire has touched the ground. If the location of the collision is found, appropriate measures should be taken; The insulation pad of a certain relay has broken down, and it is necessary to strengthen the insulation of the insulation sheet or replace the relay; The main circuit fuse often burns out, indicating that the fuse capacity is too small, and appropriate fuses should be selected; If the starting and braking time is set too long or too short, the starting and braking time can be adjusted according to the technical manual of the household elevator.

3、 After determining the point of occurrence of the fault, carefully disassemble, clean, inspect and measure according to the requirements of relevant technical specifications, determine the cause of the fault through inspection, and repair or replace according to the degree of wear and damage of the parts.

4、 When the mechanical system of the elevator light curtain malfunctions, the maintenance worker should inquire with the elevator driver, administrator, or passenger about the situation and phenomenon at the time of the malfunction. If the elevator can still operate, the driver/administrator can use a jog method to make the elevator run up and down, and the maintenance worker can analyze and determine the fault point through listening, touching, measuring, and other methods.
