The fundamental mechanism of pneumatic hoists is landing, starting, and landing. 

In addition, there are also special pneumatic hoists such as tower track type and tire type. 

The basic layout of the pneumatic hoists is composed of three departments, which are metal layout, notification mechanism, tranquility and moderation system. 

The transmission system, which may cause the pneumatic hoist to move in a certain motion, is called the pneumatic hoist. 

Due to the need for heavy transportation operations, pneumatic hoists must be scrapped, moved, rotated, lugged, climbed, and expanded, and these actions must be completed by the responding agencies.

The operation mechanism can be divided into track operation mechanism and trackless tire operation mechanism, track type operation mechanism. 

Here, only the operation mechanism is used for this railway line. 

The track operation mechanism of railway pneumatic hoists is fundamentally driven by electric motors. 

The operating mechanism consists of four departments, one motor, one brake, a reducer, and one wheel. 

The wheel device consists of a roller, an axle, bearings, and a bearing box. 

The sliding friction of the wheel rim leads to rolling friction of the wheel rim, and in order to moderate it, a degree guide wheel should be added. 

Adjacent wheels and usable axles, or single spline sleeves, etc. 

The operating mechanism of pneumatic hoists can be divided into two types, separate from centralized drivers and drives. 

The centralized drive is a two wheel operating mechanism, which is driven by an electric motor through a drive shaft. 

It is only used in conjunction with the centralized drive for small span pneumatic hoists or promotion cars. 

The self force of the control mechanism of the two driving devices driven by the two sides of the wheel is not mechanically connected.

Each mechanism of the pneumatic hoist consists of four types of devices, namely driving device, braking device, driving device, and a specialized device directly related to the effectiveness of the mechanism.

Braking device. 

The use of different types of pneumatic hoists includes various types of block type, disc type, belt type, shoe type, and cone type brakes. 

Manpower, for mechanical and hydraulic drive devices. 

The driving device is a reducer. 

Different types of pneumatic hoists use various types of helical gears, worm gears, and planetary gear reducers in different situations.

The lifting mechanism is driven by the electric power received by the driving device of the landing mechanism.

With the growth of the skills of pneumatic hoists, electric motors are used in conical brake motors, which will serve both the driving and braking functions. 

A conical brake motor, which is connected to the coupling used for motors, brakes, and gearboxes to promote further growth, has been applied to pneumatic hoists and cars, forming a very compact whole called a conical brake motor.
