CTC200·2型双机轮胎式采矿台车,是由湖南第六研究所、昆明风动机械厂、国营711矿、天水风动工具研究所于74年开始研制的,现已经过半工业性试验,初见成效。台车配用两台双向回转 YG40型导轨式凿岩机,钎头选为φ42～46毫米,最大孔深上向为4～5米,水平或倾斜为15米。台车主要应用于水平分层充填采矿法采场中凿岩,亦可用于地下峒室施工。试验表明,本台车具有体积小、重量轻、机动性好、支臂变幅动作合理、变幅范围较大,适应性强等特点,
CTC200 · 2 double-wheeled tire mining trolley, developed by the Sixth Institue of Hunan Province, Kunming Fengdong Machinery Factory, State-owned 711 Mine and Tianshui Fengdonggongju Research Institute in 74 years, has now been semi-industrialized, Initial success. Trolley equipped with two reciprocating YG40-type rail rock drill, drill bit selected as φ42 ~ 46 mm, the maximum hole depth of 4 to 5 meters, horizontal or inclined to 15 meters. Trolley is mainly used in horizontal stratified filling mining method drilling in the stope, can also be used for underground stope construction. The test shows that the trolley has the advantages of small size, light weight, good maneuverability, reasonable luffing action of the arm, large amplitude range and strong adaptability,
