What is the working principle of elevators in high-rise buildings? Want to have it or be moved?

Elevator is mainly composed of traction rope, car phase, counterweight, guide wheel, motor, reducer and brake.

The traction rope is connected with the counterweight and the car and wound on the guide wheel and the traction wheel respectively. The motor drives the traction wheel to rotate through the speed change of the reducer, and the counterweight and the car move up and down through the friction between the traction wheel and the traction rope, thus achieving the purpose of transportation.

The guide shoes on the car realize the reciprocating lifting movement of the car according to the fixed guide rails installed on the shaft wall, so as to avoid the situation that the car swings or deflects during the lifting movement.

When the motor works, the brake is released to make the elevator run. When the elevator is out of power, the brake will stop the lift of the car, maintain a static state on the designated floor, and ensure the normal entry of people and goods. As a boxcar carrying passengers, it is necessary to use a counterweight to balance the load and reduce the motor power. The compensation device of the elevator ensures the stability of the motor load and the accurate parking of the car by compensating the weight and tension changes in the movement of the traction rope.

Rack-and-pinion driven elevator, that is, escalator, has simple working principle and low technical content. Its main component is a chain endless conveyor belt, which is forced to drive and its market share is only 10%. Mostly used in airports, shopping malls, office buildings, first floor halls and other commercial places.
