鞍钢矿山公司齐大山铁矿自1988年以来投运6台国产“韶峰”牌108t电动轮汽车,对齐矿的生产起到很大作用。但由于此种车型大、箱斗高,而齐矿的主要挖掘设备是4m~3电铲,用小铲采装大型汽车有很大困难。因4m~3电铲的动臂长只有10.5m,斗杆长只有7.29m,最大卸装高度为6.3m,而108t电动轮汽车的高度为5.064m。在铲装时,电铲铲门在开斗后经常撞碰电动轮汽车的箱体,电铲动臂也经常被撞裂、撞凹,影响了装车效率。 齐矿为适应4m~3电铲采装大型电动轮运矿汽车的需要,消除采装过程中的不安全因素,解决采矿设备和运输设备相互配套问题,决定对4m~3电铲动
Anshan Iron and Steel Company Qidashan Iron Ore put into operation since 1988, six domestic “Shaofeng” brand 108t electric wheel car, the alignment of the production plays a big role. However, due to the large size of the vehicle and high tank height, the main excavation equipment of Qiwei Mine is a 4m ~ 3 electric shovel. It is very difficult to pick up a large car with a spatula. Because 4m ~ 3 shovel boom length is only 10.5m, only 7.29m long arm, the maximum unloading height of 6.3m, while the 108t electric car height of 5.064m. In shoveling, shovel shovel door often hit the electric car body after opening bucket, power shovel boom is often cracked, hit concave, affecting the loading efficiency. In order to meet the need of 4m ~ 3 electric shovel to pick up large-scale electric wheel-transporting vehicles, Qiqihar eliminates the unsafe factors in the process of mining and solves the mutual matching problems between mining equipment and transportation equipment and decides to shovel 4m ~ 3 electric shovels
