Most drilling jobs fail on the access road, not the rock. A wheeled rig that can’t climb a wet slope never reaches the hole, and every hour spent winching it out is lost revenue. YG crawler DTH drill rig solves that: tracks grip soft ground, carry the weight low, and climb grades a loaded truck can’t. YG builds 5 tracked models from 3.8T to 8T, drilling 83-165mm holes at 2.5-4km/h. Here’s what separates them, and which one fits your site and budget.
Crawler DTH Drill Rig Specifications
Five models share the same tracked chassis design and YC diesel engines. Hole diameter and horizontal reach are what separate them.

Why a Crawler Mounted DTH Drilling Rig Beats Wheeled Units
On paper, a wheeled rig is cheaper. On a real site, the difference shows up fast.
| Point | Wheeled Rig | Crawler Rig |
| Soft or wet ground | Sinks, needs matting | Floats on wide tracks |
| Slope climbing | Limited by traction | Grips and climbs |
| Ground pressure | High, concentrated | Low, spread over track length |
| Setup on rough ground | Needs a level pad | Sets up on uneven ground |
| Road travel | Faster on tarmac | Needs a trailer |
Ground pressure is the big one. A crawler spreads 6-8 tonnes across two long tracks, so it stays on top of mud, sand, and loose spoil where a wheeled chassis digs in.
Climbing matters more than speed. A 2.5km/h crawler that reaches the bench beats a 15km/h truck that gets stuck 400m short.

Where a Crawler DTH Drill Rig Earns Its Money
- Quarry benches. Drill blast holes on stepped faces where a truck can’t park level.
- Water wells in hill country. Reach village sites at the end of dirt tracks, especially in the rainy season.
- Slope stabilization and micro-piles. Work on gradients and soft shoulders where ground pressure matters.
Case: Granite Quarry in Ethiopia — 1,800m to 3,200m a Month
A quarry supplying granite aggregate to a highway project in the Oromia highlands ran a wheeled DTH rig. In the dry season it worked; once the rains came, the access tracks turned to clay and the rig couldn’t reach the upper benches. He found YG through a Google search and sent photos of the roads on WhatsApp.
We recommended the YGS180 — 6.3T, 3.6m horizontal reach, 2.5km/h tracking, drilling 90-146mm blast holes in granite.
Results over one season:
- Bench-to-bench transfer dropped from 6 hours to 2
- Monthly drilled meters rose from 1,800m to 3,200m
- No rain-season shutdown
- Payback in about 9 months

How to Choose the Right Crawler DTH Rig
Step 1: Hole diameter. 83-130mm points to YGS153. 146-165mm needs YGS300 or YGS350.
Step 2: Ground and access. Soft, wet, or sloped ground makes tracks mandatory. Hard flat pads can justify a cheaper wheeled unit.
Step 3: Horizontal reach. Drilling above track level? Pick 3.6m (YGS180) rather than 2.8m.
Step 4: Daily hours. Running two shifts? The 225L tank on YGS350 avoids refuelling stops.

Crawler Mounted DTH Drilling Rig FAQ
Q 1: How Deep Can Crawler DTH Drill Rig Drill?
Depth depends on the hammer and rod string, not the carrier. With standard 3m rods, these rigs handle 20-30m routinely, and deeper with rod changes.
Q 2: Will the Tracks Damage Paved Roads?
Steel tracks mark asphalt. For road travel, load the rig on a trailer. Track movement is for site work, not highway transport.
Q 3: How Many People Does It Take to Operate?
Two. One operator at the controls, one handling rods and the compressor connection.
Q 4: Is 33kw Enough for Hard Rock?
For 83-130mm holes in medium rock, yes. For 165mm in granite or basalt, step up to the 73.5kw YGS350.
Q 5: What’s the Lead Time and Warranty?
Standard models ship in 25-35 days after deposit. Warranty covers 12 months on structure and hydraulics, with hammers, bits, and seals available from stock.
