Main features：
1. NYD300 Crawler rock drilling rig is designed by our engineers borrowed the advanced technology from domestic and foreign countries.
2. The rig is reasonable design, complete matching, superior performance, easy to operate, easy to repair.
3. It is hydraulic drive, crawler belt. The drive head is driven by low-speed big torque motor. It has two-gear stepless speed regulating, advanced easy structure, steel wire feeding    system. The drilling rig is well stability, attractive appearance and realizes the design principle of "base on people”.
4. The diesel engine, hydraulic pump, main valve, motor, walking reduction box etc. And the main accessories are famous brand.
5. With large torque, high configuration，reasonable design, advanced control way assure the efficient working.
6. The diesel engine of the drilling rig is low emission、professional drop noise design, so it can used in various construction sites.
7. It uses advanced load sense control technology  which reduces the power consumption and heating system.
8. With nice appearance, compact structure, reliable performance, easy operation, the drilling rig is the best choice of hydraulic crawler rock drilling rigs.
9. The drilling rig can drill in the clay, sand, weathered rock, bed rock and mainly used in hydrogeology survey, water well drilling, underground tunnel, construction of vent hole, geotherm hole etc. It can apply many drilling techniques, like air drilling, foam rotary drilling.
