The Difference between Pneumatic Hoist and Electric Hoist
Pneumatic hoist has good explosion-proof performance. It is widely used in chemical industry, textile, painting, logistics, docks and other flammable, explosive, high temperature, high dust and corrosive workplaces in foreign industrialized countries.
Because of its high frequency and infinitely variable speed characteristics, it is favored by the manufacturing industries such as automobiles, tractors, motors, refrigerators and logistics industries with large output and strong continuous operation.
Especially in some industrially developed countries, it is clearly stipulated that the use of air hoists must be mandatory in flammable and explosive places such as petroleum, chemical industry, automobiles, and mines.
Pneumatic hoist
Pneumatic hoist is an upgraded product of electric hoist, which has been widely used in all walks of life. The load range varies from 250 kg to 30 tons according to different models. The pneumatic hoist can be driven only by providing a certain pressure of compressed air, which achieves low energy consumption and high efficiency.
It also has the function of gas cut-off protection to ensure that the workpiece does not fall or fall in the event of a sudden gas cut-off. Cooperating with various non-standard fixtures, the pneumatic hoist can lift workpieces of various shapes.
The installation form can be moved with a cantilever crane or a guide rail.
The difference between pneumatic hoist and electric hoist:

Pneumatic hoist |
electric hoist |
|
power |
0.6Mpa compressed air |
220V-440V voltage |
|
running speed |
Adjustable, fast speed (4 times that of electric) |
not adjustable, slow |
|
Safety |
No spark and electric shock |
Leakage, sparks, easy to get an electric shock |
|
structure |
Air motors are simpler and smaller |
Electric motors are large, heavy, and require many parts to prevent sparks |
|
Pipeline routing |
No need for cables, simple trachea connection, no need for professionals to operate |
Requires professionals to arrange, more cumbersome |
|
high temperature work |
Can work normally above 60 degrees |
It will not work properly at high temperature |
|
weight |
light |
heavier |
|
maintain |
Can be done without professional training |
Professional maintenance is required |
|
life |
The parts are machined with high precision, so they are suitable for frequent work and have a long life |
Electric motors have low efficiency, many parts are subject to wear and tear, and their lifespan is relatively short |
