1, the elevator is how to run up?
The elevator has a car and a counterweight, elevator parts through the wire rope connecting them, wire rope through the driving device (tractor) traction drive, the elevator car and counterweight elevator guide rail moves up and down.
2, the elevator rope will be broken?
Elevator wire rope is used in the elevator, the state has special provisions and requirements. The wire rope configuration not only for take the elevator car and rated load, but also taking into account the traction force size, therefore, the tensile strength of steel wire rope is much larger than the load of the elevator, the safety coefficient are above 12, usually lift more than four are equipped with wire rope, general elevator the wire rope is not broken at the same time. The safety factor of the elevator is very high if it is found that the wire rope broken, the elevator will be deactivated, to be replaced after the wire rope and then put into use.
3, the elevator operation in the sudden power outage is dangerous?
Elevator operation, such as the sudden power failure or power supply lines, the elevator will automatically stop running, there will not be any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power outage, the elevator brake will automatically brake, so that the elevator can not run. In addition, the power sector if there is a planned outage, will be notified in advance, the elevator or in advance to stop running. When the elevator is cut off, the lower part of the car is provided with a safety clamp, which can clamp the guide rail, and the car is fixed on the guide rail. Some elevator control cabinet which has emergency power supply, when the sudden power failure, the emergency power supply inside the car to the nearest floor, open the door to let the passengers safe.
4, the elevator running suddenly speed up how to do?
The running speed of the elevator either upward or downward, shall be run at rated speed within the prescribed scope is generally not speeding, if speeding in the elevator control system is overspeed prevention device (governor, when the elevator speed exceeds the rated speed of 115%, it will move), at this time, the device will automatic action, make the elevator to slow down or stop operation.
