1985年11月26日至28日武钢矿山部受冶金部矿山司的委托,在大冶铁矿主持召开了DCH-2型井下运料车鉴定会。该车是由长沙矿山研究院、苏州冶金机械厂、武钢大冶铁矿共同研制的。样机共运行了1844小时,其中地下作业1069.5小时。经检测废气,柴油机原始排放平均CO≤456ppm,NO_ω≤402ppm,均符合三部的暂定标准。该车为铰接车架,液压转向;全轮驱动,双向行驶;驱动系统由液力变矩器和液压换挡变速箱等组成;同时还具有弹簧悬挂装置和两套制动系统。其外形尺寸为5580×1780×
From November 26 to November 28, 1985, WISCO Mining Department was commissioned by the Mining Division of Metallurgical Department to hold the DCH-2 underground material carrier appraisal meeting hosted by Daye Iron Mine. The car is co-developed by Changsha Institute of Mining, Suzhou Metallurgical Machinery Factory, Wuhan Iron and Steel Daye Iron Mine jointly developed. A total of 1844 hours of prototype operation, of which 1069.5 hours of underground work. After testing the exhaust gas, the average emission of diesel engine CO≤456ppm, NO_ω≤402ppm, are in line with the three tentative standards. The car is articulated frame, hydraulic steering; all-wheel drive, two-way drive; drive system consists of hydraulic torque converter and hydraulic shift gearbox; also has spring suspension and two sets of brake system. Its external dimensions are 5580 × 1780 ×
