The invention discloses a winch hoist with a torque sensor and an encoder. The winch hoist comprises a rack, a winding drum, a gear set, a motor, a coupler and a speed reducer. The motor is in transmission connection with a rotating shaft of the speed reducer, a rotating shaft of the gear set and a rotating shaft of the winding drum through the coupler in sequence. The sensor for detecting torque and the encoder for counting the number of rotating turns are installed on the coupler. Signals are transmitted to a control system through the torque sensor and the encoder. On the one hand, the torque sensor detects the value of transmission torque of the coupler in real time, and monitors opening and closing loads of the hoist, so that it is ensured that the winch hoist normally works; on the other hand, the encoder counts the number of rotating turns of the coupler, and converts the number of rotating turns into the aperture of a lift real-time monitoring gate of the hoist. The control system ...
