Pneumatic hoist is a lifting equipment that uses compressed air as the power source to drive internal mechanical components to lift heavy objects.
It is composed of a lifting mechanism, a walking mechanism, and a gas distribution system, which has the characteristics of high frequency, stepless speed change, explosion-proof performance, and high safety factor.
There are three commonly used types of pneumatic hoists: blade type, piston type, and cylinder type。
The explosion-proof performance of the pneumatic hoist is good, and the gas distribution system uses compressed air as the power source to control the operation of the lifting hoist through the air circuit.
It is widely used in flammable, explosive, high-temperature, high dust, and corrosive places.
In addition, the pneumatic hoist can also work continuously for a long time, with low self loss, and has a safety protection design, such as a gas cut-off protection device, which can ensure that the workpiece does not fall off when suddenly cut off during the working process.
Therefore, pneumatic hoists are suitable for flammable, explosive, high-temperature, high dust, and highly corrosive places, such as petroleum, chemical, pharmaceutical, coal mines, docks, etc.
