为配套使用YGZ90外回转凿岩机,提高凿岩效率,便于钻凿较深的采矿炮孔,我们参照CTG142型双机采矿凿岩台车的推进器和扇摆机构,对OZZ-700型凿岩台车进行了技术改造,于1978年3月改造成第一台CTC141型凿岩台车,下井使用效果良好。1979年4月又改造了3台投入生产。我们将把所有CZZ-700型凿岩台车改造成为CTC141型凿岩台车。
In order to support the use of YGZ90 external rotary rock drill, improve drilling efficiency, easy to drill deeper mining blast hole, we refer to CTG142 double machine rock drill trolley propeller and fan swing mechanism, OZZ-700 rock drill station Car technology transformation, in March 1978 transformed into the first CTC141 rock drill rig, go down well with good results. In April 1979, it transformed 3 units into production. We will transform all CZZ-700 rock drilling rigs into CTC141 rock drilling rigs.
