Product Overview
Model: YTR150D | Category: Foundation Construction Equipment
The YTR150D Rotary Blasthole Drilling Rig is purpose-built for open-pit mining and quarry blasthole drilling operations. Mounted on a heavy-duty truck chassis (Caterpillar or Doosan option), this hydraulic drilling rig delivers rapid hole penetration with precise depth control, making it ideal for large-scale mining projects requiring consistent borehole quality across granite, limestone, and overburden layers.

Key Dimension
1. Doosan DE08TIS Engine
The YTR150D runs a 120 kW Doosan DE08TIS diesel, the same family of engine widely supported across export markets, giving 128 kN·m rotary torque for 1500 mm piles to 54 m.
2. Deeper 54 m Reach
At 54 m depth the YTR150D steps beyond the 45 m compact class, reaching the longer piles needed for mid-rise basements, bridge abutments and port foundations without moving to a larger rig.
3. 6–35 RPM Fast Cycle
A 6–35 r/min rotary range keeps penetration rates high on softer strata while retaining torque for mixed fill and weathered rock—a balanced all-round foundation rig.
4. 160 kN Crowd Pull
A 160 kN pulling force and 28 mm wire rope give reliable rod handling and extraction, reducing stuck-barrel risk on longer, deeper piles.

About the YTR150D Rotary Blasthole Drilling Rig
The YTR150D is the balanced mid-range rotary drilling rig: a 120 kW Doosan engine, 128 kN·m torque and 54 m depth for 1500 mm piles. It fills the gap between compact urban rigs and the large 200 mm-class machines.
It suits mid-rise building basements, bridge abutments and small port works where pile depths exceed the 45 m compact limit but do not yet need a 2000 mm rig. The Doosan engine is a familiar, serviceable choice on international sites.
Foundation contractors choose the YTR150D when they want one machine that covers most standard bored-pile jobs—enough depth and torque without the size and cost of a large rig—and can rely on global Doosan engine support alongside Yutong parts.
The Doosan engine keeps service simple on international projects, and Yutong stocks the rotary head seals, rods and wear parts most commonly needed. The 150D is often selected as the one rig a foundation fleet needs for most standard piling jobs.
The YTR150D is a common single-machine choice for foundation contractors who handle a mix of mid-rise basements and bridge abutments—it reaches the depth without paying for a larger rig, and the Doosan engine is easy to service abroad.

View DetailsWhat engine powers the YTR150D?
A 120 kW Doosan DE08TIS diesel, producing 128 kN·m rotary torque—a widely exported and supported engine family.
How deep can the YTR150D drill?
It reaches 54 m for 1500 mm-diameter piles, stepping beyond the 45 m compact class.
Why choose it over the YTR120C?
Choose the YTR150D when pile depths pass 45 m or you want the proven Doosan engine; the 120C stays for shorter, tight-access urban work.
What is the pulling force?
160 kN pulling force with 28 mm wire rope, giving reliable extraction on longer piles.
Is it good for mixed ground?
Yes—the 6–35 r/min range and 128 kN·m torque handle fill, sand, clay and weathered rock in a typical mixed foundation profile.
What markets is it sold into?
It is a popular export foundation rig across Asia, Africa, the Middle East and Latin America, supported by Yutong tooling and Doosan service networks.
