HT-25L trench-less directional drilling rig adopts steel track with rubber block. The machine is mounted on a diesel engine, a truck-Mounted extension guide, a mud mixing pump, a rotary head and convenient to move in urban areas. It also uses widely in the city or outside trench-less pipe-laying.

Characteristics:

• The traveling sheave carriage under the rotary power head makes double pushing/pulling force than provided by hydraulic motors. As a result, it saves about 25 horsepower and to be longer lifetime for chains.
• Two-speed carriage and rotary power head is in favor of mixing soil in the hole and improving the success rate and working efficiency.
• Rotary power head is three Hydraulic motors, which synchronize to drive main shaft to make it run steadily, high rotary torque. Meantime, they match with pullback reasonably.
• 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 reduces the friction and improves the lifetime of extension guide.
• Hydraulic auger anchor device saves labor force and increases efficiency.
• Two hydraulic clamps makes up and ending of drill rods more effective.
• Exclusive slide drill frame provides a range of setup angles for varying jobsites requirement.
• The diesel engine and main hydraulic parts (e.g. hydraulic pump, hydraulic valve, hydraulic motor, etc.) adopt imported products or famous domestic companies.
• Optionally available patent products: Star Anti-jamming drill rod modules, drill rig hydraulic system achieve to alarm processing for anti-jamming drill rod, drill rig to drill in and dragged back to double dynamic monitoring, automatic protection before jamming drill rod, automatically remove, automatically alarm to avoid breaking probe, breaking drill rod and other major incidents.
•  The power station uses Cummins engine of America. And it is robust and reliable.
