Trenchless drilling
Horizontal Directional Drilling Machines
Trenchless HDD rigs that install pipes, ducts and cables under roads, rivers and buildings — without digging up what is already there.
- Up to ~300 m bores
- 216 kN push-pull
- 7,000 N·m torque
How HDD works
Three stages, no open trench
- 01
Pilot bore
A steerable head drills a small pilot hole along the planned path, tracked from the surface.
- 02
Reaming
Reamers enlarge the bore to the diameter needed for the product pipe.
- 03
Pull-back
The pipe or duct is pulled back through the reamed hole to complete the crossing.

FAQs
HDD machine FAQs
Still have a question?
Our rig desk answers technical and price questions directly — no call centre.
Ask our teamChat on WhatsAppWhat is a horizontal directional drilling machine?
An HDD rig drills a steerable pilot bore under roads, rivers and buildings, then reams and pulls back pipe or duct — installing utilities without open trenches.
What can HDD install?
Water and sewer pipes, gas lines, power and telecom ducts and fibre conduits, typically in soil and soft rock.
How far can your HDD machine drill?
The listed model is rated for construction distances up to about 300 m, depending on soil. Larger bores need a different configuration — ask us.
Is HDD cheaper than trenching?
Often, once you include road restoration, traffic management and disruption. HDD also avoids damage to existing surfaces and services.
