Main features of drilling rig
The JY590-3 crawler hydraulic down-the-hole drilling rig is mainly developed for various types of mines such as quarries, cement mines, open-pit coal mines, etc. It can complete the drilling construction of main blast holes and pre-split holes. Down-the-hole drilling rigs have the characteristics of large drilling diameter, high drilling efficiency, and wide adaptability. They are widely used in the production of mining materials, coal, metallurgy, chemical industry, etc., and are also used in engineering departments such as geology, construction, hydropower, transportation, and military. Main equipment in construction.
1. The control valves are centrally arranged to facilitate the operation and control of the drilling rig. The system is reliable and simple, and the maintenance cost is low.
2. Rapidly advance and lift operations, reduce auxiliary time and improve efficiency.
3. Strengthen the cooling system to avoid high temperature shutdown and ensure reliable performance.
4. Swingable crawler chassis, easy leveling, high ground clearance, good passability and strong maneuverability.
