Tower Crane Knowledge sharing:

The cause of broken shaft of rotary motor caused by sharp reversal in tower crane slewing positioning

When the tower crane rotates, the rotation motor is broken because of the sharp reversal

If construction site is in tower crane slewing fixed position when, use the measure of quick dozen reversal, namely common name "dozen reverse car", this makes whole slewing mechanism is in bear on the foundation of normal slewing moment, added a reverse start torque suddenly again, this exceeded the rated torque that slewing mechanism place can bear greatly.

Although the input shaft of the rotary reducer is thinner than the output shaft of the rotary motor, the excessive torque will inevitably cause the output shaft of the rotary motor to fracture due to the static pressure dump hydraulic coupler s ability to isolate vibration and mitigate impact.

At present, the structure of motor - hydraulic coupling - slewing reducer - slewing support is widely used in tower crane slewing machinery in China. Large tower crane on rotary motor adopts frequency control of motor speed, or use of wound rotor asynchronous motor, start to reduce rotary speed, reduce the tower crane slewing start torque, and small and medium-sized crane due to the limitation of the cost of production,

MCT385 Tower Crane Lease Rent Hire

Use asynchronous motor or more multi-speed asynchronous motor, hydraulic coupling ease start alone, but with hydraulic coupling are drenching static pressure type, dynamic overload protection performance is poorer, the small and medium-sized crane slewing start torque is bigger, also can't effectively dynamic overload protection the institutions.
