HT-48L

HT-48L directional drilling rig adopts steel track. The drilling machine features reasonable structure, convenient operation, and high stability.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.
1.Pushing structure is chained wheel mode to reduce bearing capacity of roller chain, increase drill rig’s pullback force storage, enhance safety factor, which can save 20kw engine power.
2.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.
3.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.
4.The carriage with rollers can reduce the friction and improve the lifetime of extension guide.
5.The diesel engine and main hydraulic parts adopt imported products or famous
6.domestic companies.
7.2t hydraulic crane makes assemble and disassemble drill rods and drill tools more conveniently and flexibly and improves working efficiency.
8.Two hydraulic clamps make assemble and disassemble drill rods more conveniently and effectively.
9.Comfortable driving cab and concentrated control tower make operation more conveniently.
10.It equipped with 100hours high energy cell in order to complete long distance drilling.
