首钢重型汽车公司根据首钢矿山和国内市场的需求,从设计、样车试制到工业性试验只用了17个月的时间,就开发研制了SGA3721型42吨矿用自卸汽车,其国产化率达83.03％。首批2台样车,从1992年7月10日至1993年4月24日,在大石河铁矿完成了35000km工业性试验,在平均运距1.89km、重载连续上坡(平均6.5％)的条件下,完好率达82.5％,实际使用日历台时分别为4776h和4968h,完成运量分别为378084t和382158t,平均台年效率可达运量68万t、周转量129万tkm,柴油消耗为937kg/万tkm(ЯМЗ—240НМ型柴油机)。 1993年6月16日至17日,冶金部科技司于首钢矿业公司召开了SGA3721型矿用自卸汽车
Shougang Heavy-Duty Truck Co., Ltd. According to the demands of Shougang Group’s mines and the domestic market, it took only 17 months from the design and prototype-type trial to industrial tests to develop the 42-ton SGA3721 Dump Truck with its localization rate Up to 83.03%. The first batch of 2 prototype vehicles, from July 10, 1992 to April 24, 1993, completed 35000km industrial test at Dashihe Iron Mine, with an average distance of 1.89km and heavy continuous uphill (average 6.5% ), The intact rate reached 82.5%. The actually used calendar time was 4776h and 4968h, respectively. The completed traffic volume was 378084t and 382158t respectively. The average annual efficiency of Taiwan reached 680,000 t and the turnover volume was 1.29 million tkm. The diesel oil Consumption of 937kg / million tkm (ЯМЗ-240НМ-type diesel engine). From June 16 to June 17, 1993, the Science and Technology Department of Metallurgical Department held a SGA3721 mining dump truck at Shougang Mining Company
