2. Working Principle
The whole vehicle operating system consists of five core linkage modules: reinforced bearing chassis system, Weichai high-power mechanical power system, heavy-duty transmission power distribution system, differential lock off-road system and front hydraulic unloading system.
During daily operation, the upgraded Weichai 371HP Euro II mechanical pump engine outputs boosted low-speed torque, compared with 340HP version, it delivers stronger power output under full-load climbing and low-speed working status. Owing to pure mechanical fuel supply structure, it can stably burn low-quality local diesel without electronic alarm or shutdown failure. Engine power is transmitted to SINOTRUK 10-speed heavy transmission, and matched high-power PTO splits independent power and transmits it to the front hydraulic cylinder.
The front hydraulic assembly pushes up the large-volume manganese steel cargo box to finish one-time high-capacity rear tipping unloading, realizing efficient material turnover. The reinforced double-layer riveted frame bears heavy impact from bulk ore and earthwork; balanced suspension buffers bumpy vibration on rough roads. When driving on muddy and slippery mine roads, inter-axle plus inter-wheel double differential locks take effect, locking idle rotating wheels to increase ground adhesion, preventing vehicle trapping and sideslip.
The 6×4 dual rear drive structure averts overload chassis deformation of single-axle trucks, disperses axle load to extend chassis service life. The flipable cab realizes rapid engine detection and parts replacement to cut maintenance time. Supported by complete export certification and standard LHD steering design, it complies with traffic rules and import policies of left-traffic countries in Africa, Central Asia and Southeast Asia.
