Main Features

1. Convenient and flexible Full Hydraulic Control System
With full hydraulic control system, DFL-800A drilling rig Can always adjust the rig speed, torque, propeller shaft pressure, anti-axial compression, forward speed, increase speed conveniently and flexibly, DFL-800 DTH drilling rig can meet different geological conditions with different drilling tools.

2. Crawler Mounted Drilling Rig with High Leg Support
You can load DFL-800A drilling rig directly with high leg supports. Crawler walking is much more suitable for moving in the muddy working site.

3. Positive and negative Axle Pressure Regulator
As we know, best impact efficiency requires to match with best axial force and speed . The axle pressure of impactor is increasing as the adding of more and more drilling rods in drilling process, you can adjust the positive and negative pressure to ensure the impact to get best axial pressure. Then you can get the max drilling efficiency.

4. Rig Chassis
May be self-crawler chassis, it can be self-propelled vehicle chassis. DFL-800A drilling rig can be self-propelled crawler mounted, it can also be truck mounted according to your requirements.

5. High Efficiency
Since DFL-800A drilling rig is with full hydraulic system and top-drive rotary drilling and lifting method, which makes the rig be fit for the various drilling techniques and a variety of drilling tools. Manipulation is convenient and flexible. The drilling speed is 10-35m/hr.

6. Low Cost
Down-the-hole drilling bits is used for hard rock drilling. As you know, the DTH rock drilling is high efficiency with lowest cost drilling one meter.
