Product Overview
Model: YTQ165 | Category: Tracked Down-hole Drilling Rig
The YTQ165 is a fully hydraulic surface down-the-hole (DTH) drill rig with high-pressure dust suppression, built for blast-hole drilling in open-pit mines and quarries. With a 22 t operating weight, 338 kW engine and a 280 bar hydraulic system, it combines strong pullback, fast feed speeds and a wide hole-diameter range in one self-contained, track-mounted package.

Surface Dth Drill Rig Applications
This tracked DTH drill rig is the first stage of the drill-and-blast cycle in metal and limestone quarries, aggregates pits and open-pit mines. It drills vertical blast holes with diameters of 120–180 mm and depths up to 30 m standard, and can be adapted for pre-split and production blasting.
The undercarriage gives a 30° gradeability so the rig moves between benches on its own tracks without a separate prime mover, while the integrated air compressor removes the need for a towed compressor.
Yutong supplies this tracked down-hole drilling rig with global export support and after-sales parts, serving mines, quarries and construction contractors across Asia, Africa, the Middle East and Latin America.
Technical Highlights of the YTQ165
The independent rotation head delivers up to 3900 Nm torque at 0–100 r/min with a 5.66 m feed stroke and up to 40 kN pullback. The on-board compressor supplies 20.7 kg/cm² at 23 m³/min for clean, efficient hole flushing. Full hydraulic control gives smooth feed and precise hole alignment.
A covered cab with dust extraction protects the operator in a high-dust drilling environment, and the crawler undercarriage with 500 mm track shoes spreads ground pressure on soft bench surfaces.
How to Choose the Right Tracked Down-hole Drilling Rig
Select the DTH drill by blast-hole diameter, depth and bench height: the 120–180 mm diameter range covers most aggregate and medium-hard rock jobs. Confirm the compressor flow against your hammer size and ask Yutong to match drill rods, hammers and bits to your rock type.
As a leading blast hole drill rig manufacturer, Yutong offers configurations — bucket or body options, tyre packages, cab choices and power options — so the machine matches your exact duty cycle rather than a generic spec.

Frequently Asked Questions
What hole diameter and depth can the YTQ165 drill?
The YTQ165 drills 120–180 mm blast holes up to about 30 m deep with standard rods, configurable for deeper or larger holes with tooling options.
Does the rig include its own air compressor?
Yes. The integrated compressor delivers 20.7 kg/cm² at 23 m³/min, so no separate towed compressor is required for standard DTH hammers.
What ground conditions is it suited to?
It is designed for open-pit rock blast-hole drilling, with tracks rated for 30° gradeability on mine benches and quarry floors.
How is dust controlled?
A high-pressure dust-suppression system covers the drill steel and hole collar, reducing airborne dust and improving bit life.
Can it be matched to an electric or hydraulic shovel?
Yes — the drill benches directly ahead of loading tools; Yutong can advise on hole pattern and burden to match your shovel and blast design.
What tools wear out fastest?
DTH hammers, bits and drill rods are the main consumables; Yutong supplies matching tooling optimised for your rock hardness.
