The driven power of air hoist is compressed air, so it is also called anti-explosive hoist (air hoist). The housing of air hoist is made of aluminum, and the hoist is operated without electricity. Air hoist can be applied in severe environment with explosive, flammable substance, environment with high dust and humidity and high temperature, so it apply to chemical industry, pharmaceutical industry, foundry industry and other industries.

• air motor, piston and other precise components are handled in imported CNC.
•  Planetary gear is made of high quality steel through hardening and tempering, lubricated by extreme lithium lubricating grease
• grade T8 chain, Calibration chain with enough alloy steel.
• The dual anti-dust ball bearing is applied in the chain wheel. The load hook with ISO standard is applied. 
• apply to complex and dangerous working place.
• apply to environment with limited space
• a small quantity of components, little maintenance, long lifetime.
• Light and easy to operate.

working principle:

The energy of compressed air is turned into mechanical energy via air motor, and then the load is lifted or descended under the function of hoisting mechanism which is driven by mechanical energy.
