Efficient Hydraulic Rock Drill Manufactured

Officials and working people of the Ryongsong Machine Complex, the country’s leading machine producer, have newly manufactured a hydraulic rock drill with which to increase the tunneling speed in coal mines and mines.

Consequently, it has become possible to greatly increase productivity in tunneling units.

In order to manufacture an efficient hydraulic rock drill, they formed a powerful technical team at the complex and launched a dynamic operation and control.

The officials and researchers of the Ryongsong Machine Designing Institute pooled creative wisdom to present the structure proposal of the rock drill which suits our actual conditions in a short period.

The tool workshop played a big part in manufacturing the rock drill.

Its officials and workers devised jigs and tools by their own efforts, mindful that the shortcut to the on-schedule completion of their assignments lies in technical innovation, thus pushing ahead as planned with the processing of several spare parts which are core elements of the rock drill.

The workers of the large machine tool workshop also greatly helped toward the manufacture of the rock drill.

The new rock drill has much higher operation efficiency as compared with its predecessor.

It is said that the rock drill has very high working pressure and great moment of rotation and can increase the productivity a great deal for its high drilling rate.

The Ministry of Machine-Building Industry takes measures in order for the new hydraulic rock drill to actively contribute to production in coal mines and mines.
