HT-25L directional drilling rig adopts steel track with rubber block. The drilling machine features compact structure, convenient operation, and high working efficiency. The hydraulic system adopts the most advanced hydraulic guide control system for high efficiency and minimal operating force. It is widely used in the city or outside trench-less pipe-laying.

◆Pushing structure is motor and chain mode, the thrust force matches with the pullback force.

◆Two-speed gear is used in rotary and thrust system which is in favor of hole clearance and pullback process, and to improve working efficiency and success rates.

◆Heavy-duty Hydraulic rotary power head adopts rock drill head. It can bear a larger impact load and it is more suitable for dry or wet drilling and improves lifetime in dry or wet drilling.

◆The carriage with rollers can reduce the friction and improve the lifetime of extension guide.

◆Hydraulic auger anchor device saves labor force and increases efficiency.

◆The diesel engine and main hydraulic parts adopt imported products or famous domestic companies.
