Elevator Fixed Lifting Equipment

An elevator is a permanent service that serves a number of specific floors within a building whose car is running at least two rows of rigid orbital motion perpendicular to the horizontal plane or with an inclination angle of less than 15 ° with the vertical line. There are steps, stepping board mounted on the track for continuous operation, commonly known as escalators or automatic sidewalks. Serving the floor of the fixed lifting equipment. The vertical lift elevator has a car running between at least two rows of rigid or inclined rails with an inclination angle less than 15 °. Car size and structure to facilitate the passengers access or loading and unloading of goods. It is customary to use the elevator as a general term for vertical traffic in a building, regardless of the way it is driven. According to the speed can be divided into low-speed elevators (4 m / s below), fast elevator 4 to 12 m / s) and high-speed elevators (12 m / s or more). The mid-19th century began to appear hydraulic elevator, is still in the low-rise buildings on the application. In 1852, the United States E.G. Otis developed a wire rope lift safety lift. 80 years, the drive device to further improve, such as the motor drive through the worm drive winding reel, the use of balance weight and so on. At the end of the 19th century, the use of friction wheel drive, greatly enhance the lift height of the elevator.

At the end of the 20th century, the elevator was powered by permanent magnet synchronous traction machine. Greatly reducing the space occupied by the engine room, and has low energy consumption, energy efficient, to enhance the advantages of fast, greatly boost the real estate to the direction of high-level development.

ThyssenKrupp Elevator has developed a new "multi-lift" horizontal and vertical operation.


The engine room part, the hoistway and the bottom pit part, the car part and the standing part.


Traction system: The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of traction machine, traction wire rope, guide wheel and reverse sheave.

Guidance system: The main function of the steering system is to limit the degree of freedom of movement of the car and counterweight, so that the car and the counterweight can only move along the guide rail. The guide system consists mainly of rails, guide shoes and rails.

Elevator 7

Car: The car is the elevator component that carries passengers and cargo, and is the working part of the elevator. The car consists of a car frame and a car body.

Door system: The main function of the door system is to seal the entrance and car entrance. Door system consists of car doors, floor doors, door opener, door lock device.

Weight balance system: the main function of the system is relatively balanced car weight, in the elevator work can make the car and the weight difference between the weight to keep within the limit to ensure that the elevator traction drive normal. The system consists mainly of counterweight and weight compensation devices.

Electric power drag system: power drag system function is to provide power, the implementation of elevator speed control. Electric drive system consists of traction motor, power supply system, speed feedback device, motor speed control device and so on.

Electrical control system: the main function of the electrical control system is the operation of the elevator control and control. The electrical control system is mainly composed of the control device, the position display device, the control panel (cabinet), the flat layer device, the selection device and so on.
