HQ 20 Ton Pneumatic Hoist

20-ton pneumatic hoist for mining, working air pressure: 0.63Mpa, number of chains: 4, motor output power: 3.5KW, lifting height: standard height is 3 meters, and the lifting stroke can be customized to be extended. Full load lifting speed: 0.5M/MIN, chain size: 16*45mm, the pneumatic hoist uses a vane-type pneumatic motor as the power, and the compressed air drives the motor to rotate, and the gearbox drives the sprocket to rotate to complete the lifting work. It can run continuously because the pneumatic motor does not heat up, and the running air pressure keeps dust, dirt, moisture and corrosive gases out of the shell, running without sparks, safe and explosion-proof. It is suitable for flammable, explosive, high-temperature, high-dust and highly corrosive places such as mines, petroleum, logistics, and docks.

The figure shows a typical pneumatic motor torque and power curve at two different air pressures. The speed, torque and power of the motor decrease as the air pressure decreases. The figure shows the torque and speed curves of the pneumatic motor under two different air pressures. The speed and torque of the motor decrease as the air pressure decreases. The torque decreases significantly, while the motor speed decreases slightly as the pressure decreases.
