42T,HF-42L HDD trenchless drilling rig for cable laying

About HF-42L

HF-42L directional drilling rig adopts steel track with rubber block. The drilling machine feature 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 pipi-laying.

Techinical Characters

1  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.

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 Tow hydraulic clamps make drill rods added and removed more conveniently and effectively.

6 Comfortable driving cab and concentrated control tower make operation more conveniently.

7 It equipped with 100 hours high energy cell in order to complete long distance drilling
