Internal combustion rock drill
Detailed Product Description
Features
1. The Internal Combustion Rock Drill Type YNF30 is a hand-operated rock-drilling tool, composed of a small petrol engine, an air compressor and a rock drill.
2. During operation, the rock powder is blown away by the compressed air produced by the machine itself.
3. It carries easily with the main engine weighing only 32kg. It is suited to work on high mountains, and places with no power
supply and air compressing equipment, and especially suits the temporary projects that the machine has to be carried at any time and in any place.
4. In operation, it can be handled horizontally, vertically downward, or upward at an angle below 45°. When turned vertically downward, it can drill to the maxim depth of 6m.
5. The Double-cylinder internal combustion rock drill type YNF30 has a special subsidiary cylinder to blow away powder and enjoys a strong ability of powder displacement and a high hole-drilling speed.
Applications
1. The machine is used for rock drilling. It can be converted into a breaker or a hammer for breaking, digging, splitting and ramming by changing some components concerned.
2. It has far-ranging applicability and can be used in various environments such as high mountains, plains or in districts as hot as forty degrees centigrade or as cold as forty degrees below zero centigrade.
