The pneumatic hoist is driven by compressed air to drive the pneumatic motor to rotate, and the gearbox increases the torque after driving the sprocket to rotate and drive the chain to complete the lifting work. It is mainly composed of air motor, planetary reducer, manual control valve, main control valve, suspension assembly, brake mechanism, lifting chain, and other parts. The pneumatic hoist can be combined with explosion-proof hand trolley or pneumatic trolley to form a mobile pneumatic lifting tool. The lifting mechanism realizes the lifting and lowering of heavy objects by controlling the main control valve, and achieves the lifting and lowering positioning braking by opening and closing the brake. The chain pneumatic hoist ensures the safety of lifting operation, and the lifting mechanism of the pneumatic hoist can be fixed as a whole.

Characteristic advantages of mine pneumatic hoist:

1. Explosion-proof safety

– Powered by compressed air, 100% working cycle. The pneumatic hoist can run continuously because the air motor does not heat up. The air pressure of the operation will keep dust, dirt, moisture and corrosive gases out of the shell, no electrical danger, because no electricity is used, free from electric shock in the explosive environment, the use of aerodynamic power is a clear advantage, pneumatic hoist no spark operation, safe explosion-proof.

2. Adjustable speed

– Stepless speed adjustment when lifting or falling; Fast running speed, 3 times that of electric hoist; 5 to 10 times the hand hoist.

3. Overload protection, cut-off protection

Avoid sudden interruption of air source caused by sudden drop of load. Make the product have a further quality assurance, to avoid the overload of the load caused damage to the product.

4. Easy to operate

The pull rod control operation is simple and easy to control when lifting or lowering, so that you can quickly respond to the action of the handle output.

5. Clean, environmentally friendly, safe and reliable

The internal lubrication system eliminates air pollution. It is suitable for working in special or harsh environment such as damp, high dust, etc.

6. Easy handling

In addition to paying attention to the beauty of the appearance, the pneumatic hoist is smaller than the electric hoist, light weight, easy to carry, and the product structure design is solid, making the operation reliable and the maintenance amount small.

7. Low failure rate, durable

The pneumatic hoist is durable, and the service life is significantly longer than that of the general similar products.
