The traction lifting platform uses external power for traction and three-phase power or diesel engine for power. It is convenient and fast to move and suitable for long-distance operation. It is mainly used for field aerial work in industries such as petroleum, electric power, urban construction, post and telecommunications, etc.
Mobile lifting platform is a widely used special equipment for aerial work. Its mechanical structure of scissor makes the lift table have higher stability, wide operating platform and higher bearing capacity, which makes the range of aerial work larger and suitable for multiple people to work at the same time. It makes aerial work more efficient and safer. It is mainly used for station, wharf, Bridge, Hall, indoor and outdoor mechanical installation, equipment maintenance and building maintenance.
The fixed lifting platform is a kind of cargo lifting equipment with good lifting stability and wide application range, which is mainly used to transport goods between the height difference of production line; The materials are on-line and off-line; Adjust the height of the workpiece when assembling the workpiece; feeding of high-altitude feeder; Lifting of components during assembly of large equipment; Feeding and blanking of large machine tools; Fast loading and unloading of goods in the warehouse loading and unloading place with forklift and other carrying vehicles.
The air pump control system controls the air pump to inflate and deflate the pneumatic lifting mast through the control box in the compartment. When the pneumatic lifting mast is needed to rise, the control box makes the air pump inflate the pneumatic lifting mast by controlling the air pump control system; When the pneumatic lifting mast is needed to fall, the control box allows the pneumatic lifting mast to deflate through the control air pump control system.
The air pump control system has an automatic air pressure maintenance system, which can be installed. The mast needs to set the inflation pressure and the automatic inflation pressure. When the air pressure in the mast is less than the automatic inflation pressure, the air pump automatically starts to inflate the mast. When the gas pressure in the mast reaches the set inflating pressure value, the air pump automatically stops working.

I. INTRODUCTION
Xuedian NJXD pneumatic lifting rod is mainly made of aluminum alloy pipe, which can lift the object to a height of 30-40 meters. The maximum load capacity of pneumatic lifting rod is within 350kg, and it is convenient to transport after being put away. The disadvantage is that the wind resistance coefficient is limited, and the cable needs to be pulled. At the same time, the object carried by the top must keep the center of gravity stable, and it is not suitable to hang one side alone, which is easy to make the rod body bad.
Fixed hydraulic lift is a fixed transportation equipment that lifts articles from one height to another. Due to the large weight and volume of the lifting object, it is safe and stable, so the fixed hydraulic lift is a special form of lifting platform for aerial work, which should belong to the category of lifting machinery. As a special hydraulic lift table lift for transporting goods between floors of buildings, its main function is to carry all kinds of goods between working layers up and down; at present, the fixed hydraulic lifts on the market are mostly used for lifting cars in the height of stereo garage and underground garage, etc.

II. Technical comparison between Pneumatic lifting rod and fixed hydraulic lift
The hydraulic system of fixed hydraulic lift products is generally equipped with safety protection devices such as falling prevention, overload, power failure, etc. Other special fixed lifts are also equipped with explosion-proof electronic devices suitable for explosion-proof occasions, there are guide wheels which can make the lift table run more stably, external power units of guide rail type, the inlet and outlet of the table using hanging chain or cross bar, fence panel and lift table running warning light or warning bell, the safety switch that closes the lift table circuit when the door is opened. It is extremely generous and convenient for operators to control multiple points at each working layer, and operate in dotting mode or safe mode.
The fixed hydraulic lift has solid structure, large carrying capacity, stable lifting, simple and convenient installation and maintenance, and is an economical and practical ideal cargo conveying equipment to replace elevators between low floors. According to the installation environment and usage requirements of the lift table, different fixed hydraulic lifts can be selected and different optional configurations can be selected to complete the task of lifting articles and obtain better use effect.
If the size required for use is large, fixed Double-Span hydraulic lift can be adopted. The Double-Span hydraulic lift has stable lifting, large bearing capacity and simple operation, and is widely used in vehicle maintenance, kilns, chemical plants, equipment matching and other industries. Fixed hydraulic lift is suitable for installation and use under various indoor and outdoor environmental conditions. It can be installed in a closed shaft or between open floors according to the use requirements; It can be installed in a concave foundation pit or on a flat ground.

III. Technical comparison between Pneumatic lifting rod and rail lifting platform elevator
The biggest difference between the pneumatic lifting rod and the rail-type lifting platform elevator is that the lifting rod does not need to rely on various fixed objects and can move freely and lift freely, while the rail-type lifting platform elevator mainly uses various kinds of goods between working layers to transport up and down.
Three-dimensional garage and underground garage, two or three-storey high-rise buildings, places where pits cannot be excavated, occasions where the height of the top floor cannot reach the requirements and so on are relatively difficult to solve. The hydraulic system of the product is set to prevent falling, the upper and lower floor doors are interlinked, and Operation buttons can be set on each floor and the worktop of the lift table to realize multi-point control.
