Transmission System
| With closed double-loop hydraulic transmission system and planet decelerator, tension wheel is driven by primary gear. With inversion, the magnitude of reverse traction force is led by exit pressure of pump. | |||
| In tension condition, hydraulic motor rotation is driven by the tension wheel; the magnitude of tension is controlled by regulating the motor exit pressure. |

Characteristics
1. TY1×120III tensioning machine adopts single axle trailer structure, beautiful appearance. Front end is equipped with reversible traction tractor for easy traction.
2. Engine, main hydraulic pump, hydraulic motor, reducer, main valve block and other main components are imported parts, the system runs stably and reliably.
3. Adopt German Rexroth planetary reducer and hydraulic motor, compact structure, forming advanced closed-loop hydraulic transmission system, advanced technology, energy saving, high transmission efficiency, reliable quality.
4. Laying tension stepless adjustable, intuitive display, with good pull back function.
5. The friction disc wet brake is integrated in the planetary reducer to avoid routine maintenance. Spring brake, hydraulic release, easy operation, short response time, can realize no clearance brake, safe and reliable, in the stop state, can prevent the line operation accident caused by loose tail line.
