Passenger lifts, designed for the delivery of passengers of the elevator, requires a sound safety facilities and a certain car interior decoration.

The elevator is designed primarily for the delivery of goods and is usually accompanied by an elevator.

Medical elevators, elevators designed for transporting beds, stretchers, and medical vehicles, the car has long and narrow features.

Debris elevator, for the library, office buildings, hotels transport books, documents, food and other design of the elevator.

Sightseeing elevator, car wall transparent, for passengers to travel with the elevator.

Vehicle lift, elevator used as a vehicle.

An elevator, an elevator used on a ship.

Construction lifts, lifts for construction and maintenance.

Other types of elevators, in addition to the above-mentioned commonly used elevators, there are some special purpose elevators, such as cold storage elevators, explosion-proof elevators, mine elevators, power station elevators, firefighters with elevators, oblique elevators, nuclear island elevators.

AC elevator, with AC induction motor as the driving force of the elevator. According to the drag method can be divided into exchange single speed, AC two-speed, AC voltage regulator, AC variable frequency frequency control.

A DC elevator, a DC motor as a driving force. The rated speed of such elevators is generally above 2.00 m / s.

Hydraulic elevator, the general use of electric pump to drive liquid flow, by the plunger to lift the car lift.

A rack and pinion elevator that grinds a rail into a rack, a car that engages a gear meshing with a rack, and an electric motor that drives the elevator to lift the elevator.

Screw-type elevator, the straight top of the elevator plunger into a rectangular thread, and then with a thrust bearing the big nut installed in the cylinder top, and then through the motor by the reducer (or belt) to drive the nut rotation, so that the screw up The car ascends or descends the elevator.

A linear motor-driven elevator whose power source is a linear motor.

The advent of the elevator, had a steam engine, internal combustion engine as a direct drive to the elevator, is now basically disappeared.

There is no strict speed classification of the elevator, and China is customarily classified according to the following method.

Low speed ladder, often refers to less than 1.00m / s speed of the elevator.

Medium speed ladder, often refers to the speed of 1.00 ~ 2.00m / s elevator.

High speed ladder, often refers to the speed greater than 2.00m / s elevator.

Ultra-high-speed ladder, the speed of more than 5.00m / s elevator.

With the continuous development of elevator technology, elevator speed is getting higher and higher, the distinction between high, medium and low speed elevator speed limit is also increased accordingly.

There are drivers elevator, elevator operation by the full-time driver to complete the operation.

No elevator, passengers into the elevator car, press the control panel on the floor to go to the button, the elevator automatically run to reach the destination floor, such elevators generally have a set of features.
