Chain bucket unloader traction device is a new generation of jointly linked traction device, a kind of winding machine suitable for traction train vehicles, and the high quality product which is conducted with optimization design and and improved for many times on the basis that the technicians of our company digest the advanced technology both at home and abroad and experience. The maximum traction of the device can be up to 200KN, and can draw more than 20 heavy vehicles with complete models and specifications.

The operating characteristics of chain bucket unloader traction device: 1. The start-up speed is slow, torque is high, and speedup is level and smooth; 2. Smooth and accurate stop, strong traction and high efficiency all day long; 3. Adopt the traditional method for speed regulation: use wound rotor induction motor, and connect in series a number of resistance into the rotor circuit with collecting ring and carbon brush, and the rotate speed is controlled by the number of connected resistance which is controlled by contactor; 4. Safe and reliable for use, less maintenance and durable.

Equipment composition:

        Unloader traction device is composed of winding drive device, tensioning device, rear end buffer, intermediate pulley, roller unit guide device, steel wire rope traction rigging, ring, collar, rope clip, etc. The structure is easy to use, safe and reliable.
