Main features:
TY220F lumbering forest bulldozer is developed in response to the demands of forest working environment, TY220F lumbering bulldozer adopts the hydraulic drive and hydraulic control technologies, featuring advanced and reasonable structure, stable performances, and light and flexile operations. The forward extended rollover protection structure can effectively protect the whole machine.
- 1,A Cummins NT855C280S10 engine with 175KW rated power gives you the power and reliability you need. Improved fuel economy over the previous model with strong torque output and low fuel consumption gives you excellent overall fluid efficiency.
- 2,Quality undercarriage parts including rollers,tracks and chains ensures the stable and good performance of the dozer.Different types of the tracks can meet different working condition,like dryland,wetland and rock conditions.
- 3,TY220F forest bulldozer equipped with special lumbering ROPS shelter/cab. The wide (610mm) tracks and the mechanical winch can be equipped to achieve good trafficability and self-rescue performance and adapt to lumbering, skidding, and traction transport in the rainforests and forest farms.
- 4,The standard lumbering blade can powerfully remove all kinds of bramble obstacles along the lumbering path. The winch is used for traction of the lumbers and self-rescue of the bulldozer during the lumbering operations, of which the self-rescue function of the winch guarantees the operator’s safety.
