Audited Supplier PT320Y-1 Pengpu Good Price 320HP Crawler Bulldozer for Sale
Feature
1. The extended track ensures low ground pressure, high reliability and strong traction, contributing to precise operation;
2. The power shift transmission not only ensures smooth power shift, but also reaches target speeds and carries out directional transfers with a single control lever;
3. The wet steering clutch and brake can extend service life. They work interactively, ensuring quick and flexible steering operations;
4. The single control lever can control all blade actions;
5. The drift sealing in the drive wheel, track roller and carrier roller can prevent dust fro entering the track system, as well as lubricant leakage, thereby ensuring a long service life;
6. The hexahedron cab features wide visibility, and the insulation materials in the cab can reduce noise and vibrations;
7. The spin type fuel filter and dust separator, the air filters and the other filtration devices can prolong work time and reduce service time;
8. The comfortable cab seat can adjust upward and downward, forward and backward, meeting any positional needs the operator may have;
9. Side engine operation and the combination of a drive/brake operation system and foot brake makes overall operation of the bulldozer more rapid and convenient.
