Product Overview
Model: YTR120C | Category: Foundation Construction Equipment
The YTR120C 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.

Mobility
1. 120 kN·m Torque for 1.5 m Piles
The YTR120C delivers 120 kN·m of rotary torque at 110 kW, rated for pile diameters up to 1500 mm and depths to 45 m. It is the compact end of the YTR range for urban and light foundation work.
2. Fast 6–28 RPM Rotation
A 6–28 r/min rotary speed lets the head run fast on loose material and back off on harder layers, keeping cycle times up on bored piles through mixed fill and clay.
3. Light, Site-Friendly Footprint
At roughly 70 t working weight the YTR120C accesses restricted urban and industrial sites where larger rigs cannot enter, supporting basements, bridge piles and small commercial foundations.
4. Proven Bored-Pile Tooling
Standard bucket, auger and core-barrel tooling fits the YTR120C, so it handles the common fill, sand and clay conditions of urban foundation contracting without custom adaptation.

About the YTR120C Rotary Blasthole Drilling Rig
The YTR120C is the entry rotary drilling rig in the YTR line, built for 1500 mm-diameter bored piles to 45 m. It targets urban foundation work—basements, light bridge piles and commercial building foundations—where site access is limited and the ground is mostly fill, sand and clay.
Its compact 70 t class size means it can be positioned on tight urban plots, yet it still carries the torque and crowd to produce quality piles through soft to medium strata. The fast rotation suits contractors chasing cycle time on repeat pile grids.
For foundation contractors in Asia, Africa and the Middle East, the YTR120C is the practical starter rig: enough capacity for most urban piling, simpler to transport and service, and backed by Yutong tooling and parts supply.
For urban foundation contractors, the YTR120C is the practical entry rig: it transports easily between city sites, fits tight plots, and uses standard bucket and auger tooling stocked by Yutong dealers. Tell us your pile grid and the team will size the tool set.

View DetailsWhat is the YTR120C pile diameter and depth?
It is rated for up to 1500 mm diameter piles and 45 m depth, with 110 kW engine and 120 kN·m rotary torque.
Is it suitable for urban basements?
Yes—at around 70 t it is the compact end of the range and accesses tight urban sites that larger YTR rigs cannot reach.
What ground conditions does it handle?
It handles fill, sand, clay and silt with bucket, auger and core barrel tooling; very hard rock needs a DTH or core approach specified during configuration.
How does it compare with the YTR150D?
The YTR120C is the lighter, faster compact rig; the YTR150D adds a Doosan engine and reaches 54 m depth. Step up to the 150D when depth grows beyond 45 m.
What tooling is standard?
Bucket, auger and core barrel tooling are supported; tell us the ground conditions and we will recommend the tool set for your pile design.
Can it be used for blasthole drilling?
The YTR120C is a bored-pile rig; for open-pit blasthole patterns the dedicated blasthole rigs are the correct match, though it can undertake small-diameter rock work with the right tooling.
