1973年下半年我们参照河北铜矿、华铜铜矿研制的斗车经验,研制了两种适用于1.1米~3U型固定矿车的金研-55型八轮转载斗车(见图1),它是我矿与双机液压凿岩台车、华一型装岩机配套使用的主要设备。它具有结构简单,制造容易,装运效率高,减轻工人劳动强度,适用小断面巷道掘进,无需专制矿车等优点。 In the second half of 1973, with reference to the experience of fighting a car developed by Hebei Copper Mine and Huacai Copper Mine, we developed two types of Jinyan-55 eight-wheel loader (see Figure 1) suitable for 1.1m-3u fixed- , Which is the main equipment that I mine and double hydraulic rock drill trolley, Huayi type rock loader supporting the use of. The utility model has the advantages of simple structure, easy manufacture, high shipping efficiency, reducing labor intensity of a worker, suitable for excavation of a small section roadway, and no need of an autocar.
