The wire rope will break, because the state has special regulations on wire ropes for elevators.

And the wire rope is not only configured to bear the car and rated load, but also

Considering the tension, its tensile strength is much higher than the bearing capacity of the elevator.

Generally, elevators are equipped with more than 4 wire ropes, so elevators will not easily fall into the shaft.

Passengers trapped in the elevator should not panic, and never try to climb out of the elevator by themselves.

You should try to inform the maintenance unit, and you can use the phone in the elevator for help. If there is no telephone,

You can knock at the door and shout, or you can knock with your shoes. If no one really responds, it is safest.

The way is to stay calm, save your strength and wait for help.

Elevator profile:

Elevator is a kind of vertical elevator powered by motor, equipped with box-shaped pod, which is used to transport people or goods in multi-storey buildings. There is also a step, the pedal is installed on the track and runs continuously, commonly known as escalator or moving sidewalk. Fixed lifting equipment serving designated floors. The vertical elevator has a car, and the car runs between at least two rows of rigid guide rails with vertical or inclined angles less than15. The size and structure of the carriage are convenient for passengers to enter, exit or load and unload goods. Traditionally, regardless of its driving mode, elevators are regarded as the general term for vertical transportation in buildings. According to the speed, it can be divided into low-speed elevators (below 1m/s), fast elevators (1m/s) and high-speed elevators (above 2m/s). Hydraulic elevators began to appear in the middle of19th century and are still used in low-rise buildings. In 1852, Otis Company of the United States, for example, developed a safety elevator for wire rope hoisting. In the 1980s, the driving device was further improved, such as the motor driving the drum through worm drive, and the counterweight was adopted. At the end of 19, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.

Function:

Modern elevators are mainly composed of traction machines (winches), guide rails, counterweight devices and safety devices (such as speed limiters, safety tongs and buffers). ), signal control system, car and hall door, etc. These components are installed in the shaft and machine room of the building respectively. Usually, steel wire rope is used for friction transmission. The steel wire rope bypasses the traction sheave, and its two ends are respectively connected with the car and the counterweight. The motor drives the traction sheave to lift the car. Elevator requires safety and reliability, high conveying efficiency, accurate leveling and comfortable ride. The basic parameters of the elevator mainly include rated load, number of passengers, rated speed, overall dimensions of the car and shaft type. The use method is simple.

Classification:

Passenger elevators, designed for transporting passengers, need perfect safety facilities and certain internal decoration.

Freight elevators are mainly used to transport goods, usually equipped with manned elevators and necessary safety devices.

The medical elevator is designed for transporting sickbeds, stretchers and medical vehicles, and has the characteristics of a long and narrow car.

Residential elevators, elevators designed for residential buildings, generally choose the lower centralized control mode, and the interior decoration of the bridge car is simple.

The utility elevator is designed for libraries, office buildings and restaurants, and used to transport books, documents and food. Personnel are not allowed to enter the elevator, and there is no necessary passenger safety facilities.
