The Problem

Rock Shouldn’t Mean Spending more on a Rig

Most HDD contractors are forced into buying expensive “all-terrain” rigs to handle rock — even though rock is only a portion of their work. These machines cost more to own and are often overkill for everyday drilling.

The Goodeng G30 is an exceptionally capable rig for mixed ground, clay, sand, and urban conditions — but like most dirt/clay rigs, hard rock is its natural limitation. Until now.

What Happens in Hard Rock

Without an air hammer system, hard rock conditions mean:

✕

Penetration slows dramatically, stalling production

✕

Tooling wear accelerates, increasing replacement costs

✕

Thrust and torque systems are overstressed

✕

Jobs are delayed, rescheduled, or declined entirely

✕

Contractors consider upgrading to rigs they don’t actually need

Three Components. One Complete Rock-Capable System.

We’ve engineered a rig + system combination that transforms the G30 into a true all-terrain drill — without the downsides of traditional all-terrain machines.

1

Goodeng G30 HDD Rig

Primary Platform

A compact, powerful, and highly productive HDD rig designed for tight access, urban works, and mixed ground conditions.

Thrust / Pullback~130kN / 29,200 lb
Torque~5,400 Nm / 3,830 ft-lbs
Engine~110kW / 147HP Diesel
Mud Flow~200 L/min / 53 g/min

2

High-Pressure Diesel Air Compressor

Power Source

Delivers 17 bar as standard, with a manual pressure dial allowing output to be increased up to 21 bar when required. Trade airflow volume for pressure — ideal for harder rock conditions where impact energy matters most.

Standard Pressure17 Bar
Max PressureUp to 21 Bar
Airflow~605 CFM
EngineCummins Diesel

3

Pioneer One 3″ CR Air Hammer

Rock Breaker

Purpose-built for HDD, delivering aggressive yet controlled percussive drilling. Integrates seamlessly with HDD rigs and is optimised for efficiency, steering, and durability.

Type3″ CR Steerable
ApplicationHDD-Specific
Water Requirement~1–2 GPM
LocatingCompatible with DCI, Subsite, & U-Mag

How It Works

One Machine. Two Modes. Any Ground.

Switch from standard to rock drilling without changing rigs or mobilising additional equipment.

01

Standard Mode

G30 operates as a conventional directional drill for dirt, clay, sand, and mixed ground.

→
02

Rock Mode Activated

Air Hammer systems are engaged. Percussion drilling fractures rock at the bit while maintaining steering control.

→
03

The Result

The same machine now performs confidently in hard rock environments — no compromise, no machine change.

The System

The Advantage

A Smarter Way to Achieve All-Terrain Capability

Instead of relying on brute-force thrust and torque alone, this system introduces high-impact percussive drilling — fracturing rock efficiently while maintaining steering control.

⚡

More Efficient in Rock

Impact energy is delivered directly to the bit — no reliance on brute rotation through hard formations.

🛡

Less Punishing on the Rig

Percussion absorbs the load. Reduced stress on thrust, torque, rods, and drivetrain extends rig lifespan.

↔

More Versatile Across Jobs

Deploy air only when rock is encountered. The rest of the time, the G30 runs as an efficient, compact dirt drill.

$

Lower Capital Investment

Avoid the premium cost of dedicated all-terrain rigs. Expand capability without expanding fleet size.

Why This Matters

This Is Not an Accessory Upgrade.
It’s a Strategic Rethink.

This combination is often overlooked in the market. Contractors are rarely shown that there’s a better path to all-terrain capability.

You don’t need to start with an all-terrain rig.
You can build all-terrain capability through the right system.
A modular approach can outperform traditional solutions in both cost and performance.

Who This Is For

Built for Contractors Who Want More From Their Rig

Contractors upgrading from 5T–10T rigs
Operators encountering increasing rock conditions
Businesses wanting rock capability without massive investment
Regional contractors requiring maximum versatility
Fleet owners wanting modular scalability
