Hoisting mechanism of crane



The utility model provides a hoisting mechanism of crane, include: reel group, speed reducer, motor and torque limiter. Reel group is through curling up or releasing rise or the descending of wire rope in order to drive the lifting hook, the speed reducer pass through the reel shaft coupling with the reel group link, the motor is used for doing hoisting mechanism of crane provides start -up force moment, torque limiter respectively with the motor with the speed reducer is connected, is used for the monitoring the torque value of the input axle head of speed reducer, when the torque value of torque limiter monitoring is greater than when booking torque value, torque limiter disconnection with the motor with the connection of speed reducer can in time stop the lift action of lifting hook, and effective timely avoid accident takes place.
