It is the generator for mine electric wheel dump truck special use, and applies to AC variable frequency variable pressure electrical transmission power system, which ensures that operating diesel generator set can offer the rated output power in most working condition. It effectively reduces fuel consumption and pollution, and energy saving effect is achieved. According to dump truck operation condition, it properly increases structure strength, and improves generator' ability of anti-vibration and capability of bearing shock load, which guarantees the service life of generator.
