HT-48L trench-less directional drilling rig adopts steel track .The machine is mounted on a diesel engine, a hydraulic crane, 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 store, enhance safety factor, save 20kw engine power.
  •  Comfortable driving cab and concentrated control tower make operation more conveniently.
  • 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.
  • Exclusive slide drill frame provides a range of setup angles for varying jobsites requirement.
  • 2t hydraulic crane makes assemble and disassemble drill rods and drill tools more conveniently and flexibly and improves work efficiently.
  • 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.
  • Optionally available patent products: Star Anti-sticking drill rod modules, drill rig hydraulic system achieve to alarm processing for anti-sticking drill rod, drill rig to drill in and dragged back to double dynamic monitoring, automatic protection before sticking to drill rod, automatically remove, automatically alarm to avoid breaking probe, breaking drill rod and other major incidents.
  • Optionally available system: mud mixing system.
  • The power station uses Cummins engine of America. And it is robust and reliable.
  • The diesel engine and 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.
