The manual winch is a kind of lifting tool suitable for many places. It can carry out vehicle self rescue in the harsh environment. Under other conditions, the hand winch is an indispensable safety device for military police, petroleum, hydrology, environmental protection, forestry, traffic, public security, border defense, fire fighting and other field operations. With the built-in mechanical brake, the handle rotates clockwise to wind up, counterclockwise to wind down, and the brake is automatically applied at the stopped position to stop the load. This type is fit for schools, public facilities, places accessible to unidentified numbers of people, or other places where the winch may malfunction if its stopper arm, which is able to release the brakes, protrudes from the system itself. With the stopper mechanism contained in a hermetically enclosed special clutch cover, you can work to wind up and down the target equipment without the risk of malfunction.
