260m Multi-purpose Down-to-hole Drilling Rig DFL-200S with DTH Bit and DTH Hammer for Hard Rock

Multi-purpose DTH Drilling Rig DFL-200S for Borehole

The water well drilling rig is a high efficiency top drive , multi-purpose full hydraulic drilling rig, with advantages of advanced technology, ease operation, high efficiency, reliability and durability, widely applicable to drilling water wells, test wells, dewatering well, relief well, geothermal air conditioning hole, coal bed methane, natural gas, oil exploration and other projects, the rig applicable to various stratum by air DTH drilling, has high drilling speed for rock with Platts hardness of f=4-20.

Multi-Purpose Drilling Rig
Various drilling processes are available on this rig, such as DTH drilling, through-air reverse circulation drilling, air lifting reverse circulation drilling, cutting drilling, cone bit drilling, core drilling and so on. Mud pump, foam pump, generator etc. can be added according to customers' requirements.

High Efficiency
Since DFL-200S 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.

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.

Main Features

1. Convenient and flexible Full Hydraulic Control System
With full hydraulic control system, DFL-200S drilling rig Can always adjust the rig speed, torque, propeller shaft pressure, anti-axial compression, forward speed, increase speed conveniently and flexibly, DFL-200S 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-200S drilling rig directly with high leg supports. Crawler walking is much more suitable for movng 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-200S drilling rig

can be self-propelled crawler mounted, it can also be truck mounted according to your requirements.

Engineers were sent to train the operators of HDD rig overseas

1. Professional technical support pre-sale, sale and after-sale.
