太原重型机器厂根据原一机部、冶金部、燃化部联合下达关于研制8～12米~3矿用挖掘机的任务,经过多年改进和完善,终于研制成功。这是我国自行设计研制的第一台大型矿用挖掘机,采用齿轮齿条推压,独立式行走传动机构、气囊式力矩限制器、二硫化钼尼龙套、四联动主令控制器和抗干扰能力强的可控硅触发装置等最新结构。1984年12月下旬,三个部联合组成
Taiyuan Heavy Machinery Factory based on the original Ministry of the Ministry, the Ministry of Metallurgy, the Department of Combine the Department issued a development on the 8 ~ 12 meters ~ 3 mine excavator tasks, after years of improvement and improvement, and finally successfully developed. This is China’s first large-scale mine excavator designed and developed by our company. It adopts rack and pinion pushing, independent type traveling transmission mechanism, airbag type torque limiter, molybdenum disulfide nylon sleeve, four linkage master controller and anti-jamming. High-performance thyristor triggering device and other latest structures. In late December 1984, the three departments formed a joint
