PRODUCT HIGHLIGHTS
The development of Weichai's WP12 off-road four-stage engine started early, has a high degree of maturity, and has been verified by three high experiments.
Silicone oil clutch suction fan, low energy consumption.
The transmission speed ratio is 1:1, the steering oil pump has a low speed and high reliability.
Long-lasting fuel filter with longer maintenance interval (5000km/500h).
TRANSMISSION
Double intermediate shaft design, large head gear ratio (up to 9.14), strong climbing ability
Single-box double-intermediate shaft structure, no sub-box,It is easy to operate and highly reliable
Large center distance (170), intermediate shaft segmented design,Three-point support, long life of rotating parts
Inverted bevel tooth design to prevent gear dropping;New positioning method of two-shaft gear + segmented double;Key design, effectively reduce the failure rate
According to the actual working conditions of mining vehicles, the speed ratio is designed,The low-gear speed ratio is smaller, which is more suitable for mining conditions
AXLES
Front axle: 20 tons, middle and rear axles: 35 tons
Hande axle, market share of more than 90%
CAB
The full-skeleton wide-body cab (Figure 1) has greater space utilization than competing narrow-body cabs, is spacious and comfortable, and has an oversized windshield with a wide field of view, improving active safety.
More reasonable ergonomics: interior, instrumentation, and controls.
Powerful cooling, with a cooling capacity of 4800W, optimized cab air conditioning outlet piping, which is conducive to the release of cold/heat. The enlarged condenser is supplemented by an imported electronic fan, making the system more stable and reliable.
The door adopts an integral double sealing structure to effectively prevent dust from entering. It has passed the smoke test and has excellent sealing effect.
Wide-body driving can be turned forward 46° (Figure 2) to facilitate engine and other vehicle maintenance work
Mechanical air conditioning is standard
After the test of high temperature in Hami area, Xinjiang, the reliability is better.
The condenser assembly with large heat dissipation capacity is arranged at the front of the cab platform, with low heat exchange interference and superior heat dissipation performance
Variable displacement air conditioning compressor assembly, energy saving and fuel saving.
