An indispensable vertical transport in elevator-type high-rise buildings, it is a large and comprehensive equipment of mechatronics. In order to ensure its safety and reliability, the elevator has set up preventive measures from various aspects, such as electrical safety devices and mechanical safety devices. Among them, the electrical safety device includes: power control protection device, power supply phase sequence protection device, door lock electrical interlock device, emergency stop switch switch, overspeed protection switch, overload protection switch, limit switch, emergency stop switch, safety window switch Wait. Mechanical safety devices include brakes, speed limiters, safety gears, bumpers, door hook locks, door safety touch panels, and the like. These safety devices ensure the safe operation of the elevator. In the face of the knowledge of the elevator passenger elevator company made a question and answer introduction.

1. How does the elevator 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 (the traction machine), so that the elevator car and the counterweight move up and down on the inner rail of the elevator.

2. Will the wire rope of the elevator break?

For wire rope elevators used in elevators, the state has special regulations and requirements. The configuration of the wire rope is not only to bear the elevator car and the rated load, but also considers the magnitude of the traction force. Therefore, the tensile strength of the wire rope is much larger than the load capacity of the elevator. Their safety factors are all above 12, and the general elevators are all With more than four wire ropes, the elevator wire rope will not break.
