Abstract
A winch includes a power mechanism motor or a hydraulic motor, a transmission, a winding drum, a brake, a machine frame and a sensor. The transmission, the winding drum, the brake, the machine frame and the sensor are arranged in the winding drum. A driving shaft penetrates through a central hole of a central sun gear of each planetary gear. A clutch gear shifter is arranged between each planetary gear stage, the last planetary gear stage and the winding drum. The clutch gear shifter is connected with a power input side planetary gear rack and a power output side central sun gear during neutral gear. The driving unit drives the execution unit tubular member to move to the right side, and the clutch is disconnected from the connection with the left planetary gear. The right driving shaft power output gear is combined with the central sun gear to complete gear shifting. The empty hook or light-load power mechanism directly drives the winding drum to rotate through the driving shaft.
