Main Feature:
1. Full hydraulic control is convenient and flexible
The rig's speed, torque, thrust axial pressure, reverse axial pressure, thrust speed, and lifting speed can be adjusted at
any time to meet the requirements of different drilling tools and different construction processes
2.Top-drive slewing propulsion lifting
It is easy to connect and disconnect the drill pipe, shorten the auxiliary time, and also facilitate drilling with the pipe.
3.Multifunctional drilling
Various drilling processes can be used on this rig, such as: down-the-hole drilling, through-air reverse circulation drilling,
gas lift reverse circulation drilling, cutting drilling, roller drilling, tube drilling, and Core drilling under development and
more. The drilling rig can be equipped with mud pumps, foam pumps and generators according to user needs. The rig
is also equipped with various hoists as standard.
4.High efficiency
Due to the full hydraulic and top-drive slewing propulsion lifting, it is suitable for various drilling processes and various
drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so the operation efficiency is high.
5.Low cost
DTH drilling is mainly based on DTH drilling technology. DTH rock drilling has high efficiency and lower cost per meter.
6.High outrigger tracked
The high outriggers are convenient for loading and transportation, and can be loaded directly without crane. Tracked
walking is more suitable for muddy field movement.
7.Positive and negative axial pressure adjustment
The optimal impact efficiency of each impactor has its matching optimal shaft pressure and speed. During the drilling process,
as the number of drill pipes increases, the axial pressure on the impactor also increases. Therefore, the positive and
negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more suitable
axial pressure. At this time, the impact efficiency is higher.
8.The role of the oil mister
Patented oil mister and oil mist pump. During the drilling process, the high-speed impactor is lubricated at all
times to prolong its life.
9.Rig chassis
It can be a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis.
