Air winch is a kind of manual operated single drum type air winch. It adopts 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, this winch is specially designed with hand brake and foot brake. This winch is widely used for drilling, marines, minings, engineering sites, etc to pull heavy cargo. Features: 1. Small in size, light in weight, high in mobility. 2. Variable speed control, flexible to perform clockwise and anti-clockwise rotation. 3. High practicability with anti-explosive function, especially stable and reliable in inflammable, explosive, wet, damp, and other extremely working environments. 4. High starting torque enables start with load. 5. Anti-overload function.
