Main features of drilling rig:
1. The drilling rig is mainly mechanically driven, and the others are hydraulically driven, effectively using power. The overall power loss is small and the drilling cost is low.
2. The drilling rig has more positive speed series and 14-500r/min speed range, and the output torque is 13428-250N.m.
3. The drilling rig has 2 reverse speeds for easy handling of accidents.
4. The drilling rig adopts a mechanical power head with a long-stroke double-speed mechanism, and the power head has a stroke of 3800mm, which is used to improve the drilling efficiency and reduce the occurrence of drill blocking and burning accidents.
5. The drilling rig uses double oil pumps for oil supply, a single pump is used when drilling, and a double pump is used for confluence when lifting and lowering the drill; the power loss is small and the auxiliary time is short.
6. The drilling rig has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.
7. The tracked chassis is adopted, and the outrigger cylinder stroke is 1.5m.
8. The drilling rig reserves some functional interfaces in the hydraulic system, which can be expanded according to the technological requirements of different users.
