How to solve the failure of the kitchen ladder
whenChuan LadderWhat should we do when an abnormal situation occurs in the work?
One: How does Chuancai Ladder work?
The elevator has a car and a counterweight, which are connected by a wire rope. The wire rope is driven by the traction of the driving device (traction machine), so that the elevator car and the counterweight move up and down on the inner guide rail of the elevator.
Two: Will the elevator rope break?
The steel wire rope for elevators is special for elevators, we have special rules and requirements. The configuration of the wire rope is not only to bear the elevator car and additional load, but also considers the size of the traction force. Therefore, the tensile strength of the wire rope is much greater than the load of the elevator, and their safety factors are all above 12, and the general elevators are equipped with More than four wire ropes.
Three: Is there any risk of a sudden power outage while the kitchen ladder is running?
If there is a sudden power failure or the power supply line fails during the operation of the elevator, the elevator will automatically stop the operation without any risk. Due to the electrical and mechanical safety devices installed in the kitchen ladder, once the power fails, the elevator brake will automatically brake, making the elevator unable to run. In addition, if there is a planned power outage in the power supply section, it will be notified in advance, and the elevator may be suspended in advance.
Four: What should I do if the operation of the kitchen ladder suddenly accelerates?
Whether the elevator's operating speed is up or down, it should be operated within a regular extra speed range. Generally, it will not overspeed. If overspeed is present, there is an anti-overspeed device in the elevator control system. At this moment, the device will automatically start. Slow down or stop the elevator.
Five: Can the elevator car overload be controlled automatically?
The load capacity of the elevator is different according to the needs. The elevator can only run within the regular load capacity. When it exceeds, the elevator will automatically alarm and cannot run.
