Drill Rigs and Machinery of Epiroc（二）
In the mid-1950s, manufacturers began to apply hydraulic technology to the control system of drill rigs. In addition to the impact system and rotation system of drifters, the rotation, feed and walking systems of drill rig were all hydraulically controlled. The system greatly shortens working time and improves production efficiency.
