HT-42L directional drilling rig adopts steel track. The machine is mounted on a diesel engine, a drill frame, a mud pump, and a rotary head and convenient to move in urban areas. It also used widely in the city or outside trench-less pipe-laying. Hydraulic system adopts pilot control for remote and minimal operating force.
Characteristics >>
> Pushing structure is chained wheel mode to reduce bearing capacity of roller chain, increase drill rig’s pullback force storage, and enhance safety factor, which can save 20kw engine power.
> 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.
> Exclusive slide drill frame provides a range of setup angles for varying jobsites requirement.
> Two hydraulic clamps make assemble and disassemble drill rods more conveniently and effectively.
> Rotary power head is driven by three Hydraulic motors with stable movement and high rotary torque. Meantime, they match with pullback force reasonably.
> The power station uses Cummins engine of America. And it is robust and reliable.
> The main hydraulic parts (e.g. hydraulic pump, hydraulic valve, hydraulic motor, etc.) adopt imported products or famous domestic companies.
> It equipped with 100hours high energy cell in order to complete long distance drilling.
