There are dozens of elevator classifications. According to different classification methods, the types of elevators are different, as follows:

1. Classification by use: It can be divided into passenger elevators, freight elevators, hospital elevators, sundries elevators, sightseeing elevators, vehicle elevators, ship elevators, construction elevators, and some special-purpose elevators.

2. Classification by driving mode: It can be divided into AC elevator, DC elevator, hydraulic elevator, rack and pinion elevator, screw elevator.

3. Classification by speed: It can be divided into low-speed elevators, medium-speed elevators, high-speed elevators and ultra-high-speed elevators.

4. Classification according to whether there is a driver: it can be divided into two types: elevator with driver and elevator without driver.

5. According to the control method: it can be divided into handle switch control elevator, button control elevator, signal control elevator, collective selection control elevator, parallel control elevator and group control elevator.

AC elevator, an elevator that uses an AC induction motor as a driving force. According to the drag mode, it can be divided into AC single-speed, AC double-speed, AC voltage regulation and speed regulation, and AC variable voltage and frequency conversion speed regulation. A DC elevator is an elevator that uses a DC motor as a driving force. The rated speed of this type of elevator is generally above 2.00m/s.

Hydraulic elevators generally use an electric pump to drive the flow of liquid, and lift the car up and down by a plunger. Rack and pinion elevator is an elevator in which the guide rail is processed into a rack, the car is equipped with a gear that meshes with the rack, and the motor drives the gear to rotate to lift the car.

For screw elevator, the plunger of the straight top elevator is processed into a rectangular thread, and then the large nut with thrust bearing is installed on the top of the oil cylinder, and then the nut is rotated by the motor through the reducer (or belt), so that the screw is lifted. An elevator in which the car goes up or down.
