Y19A Hand-hold and Air-leg Rock Drill
Instruction
Y19A rock drill is mainly used in samll quarries, small coal mines and limestone mines for drilling, blasting for constructing roads in mountain areas, also in the capital construction for water conservancy works. It is suitable for drilling works in large mines for boulder blasting and other projects as well. When it is matched with air- leg model FT100, it can perform both dry and wet drilling under various kinds of rocks, and it is evenmore flexible in drilling operation when matched with the small- size compressor of capacity of 1.5m3, the function will be better than others.
The flanged control vavle is adopted, so it has many advantages such as reasonable in structure, quick in starting, light in weight, fast drilling speed, lower air comsumption, smaller vibration, easier operation, lower trouble rate, long-life parts, good economic effect, ect. It is also equipped with a rubber damping handle, so is eary to operate and provide the operators with necessary working protection.
