air winch.Its adopt compressed air as its power to drive air motor to drive 

air motor, driving drum via two grades gears ( to reduce transmitting speed 

and enlarge torque) so as to lift and drag heavy cargo. Considering security,

these winches are equipped with hand brake, foot brake, air friction plate

brake or air cylinder brake. These winches are widely used for drilling, marines, 

minings, engineering sites, etc to pull heavy cargo.

Main Features:

1. Equipped with cylinder air brake , which enables the winch automatically in brake when stops.

2. Variable speed control, flexible to perform clockwise and anti-clockwise rotation.

3. Compact in size, light weight, portable to move and easy to install.

4. High practicability with anti-explosive function, especially stable and reliable in inflammable,explosive,wet,damp,and other extremely working environments.
