ST 300 Meters Large Pneumatic Borewell Machine Main Advantages:
1. The speed range of the drilling rig is 14-1030r / min, and the maximum output torque is 9500n. M.
2. The drilling rig adopts long travel speed doubling mechanism and mechanical power head with a stroke of 3500mm, which is used to improve drilling efficiency and reduce drilling plugging and burning accidents.
3. The drilling rig adopts double oil pumps for oil supply, single pump for drilling and two pumps for combined flow for lifting and tripping; Less power loss and short auxiliary time.
4. Crawler chassis is adopted, the stroke of outrigger cylinder is 1.5m, it can be loaded automatically, and it is convenient to move and transport.
5. The drilling machine is in mechanical operation. Some functional interfaces are reserved in the hydraulic system, which can be expanded according to the process requirements of different users.
