Fuel-Powered Rotary Drilling Rig for Piling & Foundation

The YTR230Dpro suits mid-size bored piles around 1.0–1.5 m diameter and 40–60 m depth for building and light bridge work. Step up to the YTR300Dmax for 1.5–2.0 m diameters and the YTR360Dpro for the 2.0–2.5 m, 80–90 m bores typical of railway and major bridge foundations. Sizing to the actual pile avoids hauling an oversized mast across rough access tracks.

Loose sand and clay take a double-flask boring bucket; gravel and cobbles need a rock bucket; hard weathered rock needs a DTH hammer or core barrel. Tell us the soil profile from your site investigation and we will spec the rotary head torque and the tooling set so the crew is not switching tools on the job.

A fuel-fired rig needs a fuel bowser on site and a planned refuel schedule across two shifts. For export, tell us the destination country so the engine is calibrated to the required emission standard — Euro II for remote, less-regulated markets or Euro V where environmental rules apply. We then quote the complete export documentation set with the rig.

Long linear projects cross remote countryside with no power. Recommended class: YTR300Dmax or YTR360Dpro diesel rigs for the large, deep bridge piles, refueled from a mobile bowser.

Wharf and quay walls need large-diameter piles over water. Recommended class: larger fuel-fired rig with a platform barge arrangement and the torque to drive through soft marine clay into bearing stratum.

Plant sites are often remote and noisy anyway. Recommended class: YTR230Dpro or YTR300Dpro diesel rigs, where the self-contained power supply beats any charging argument.

Even with power, a diesel rig is chosen where two-shift continuous drilling matters more than emissions. Recommended class: mid-size fuel-fired rig for deep basements and metro box piles.

Dam abutments and spillways are in rural, power-free locations. Recommended class: fuel-fired rotary rig with the reach and torque to drill through fill and weathered bedrock.

A fuel-fired (diesel) rig carries its own power supply, so it keeps drilling on remote sites with no grid connection, delivers high continuous torque for hard strata, and can run two shifts without a charging break. A load-sensing hydraulic system keeps fuel consumption per drilled meter low.

The YTR230Dpro, YTR300Dmax and YTR360Dpro series cover bored piles from roughly 600 mm to 2.5 m diameter and depths up to 90 m, depending on mast and tooling. Larger models are matched to bridge and metro piles; smaller models suit building foundations.

Yes where the job is off-grid. A diesel rig refuels in minutes and needs no substation or charge pad, which is why contractors keep fuel-fired rigs for greenfield highways, mines and cross-country pipelines. Choose electric only when the site has power and low-emission rules apply.

The load-sensing hydraulic system only draws engine power when crowd and rotation demand it, rather than idling at full flow. Combined with a torque-converter-matched engine, this cuts liters consumed per drilled meter compared with older constant-flow rigs.

The fuel-fired rotary drilling rig handles clay, sand, silt, gravel and moderately weathered rock. For hard rock a DTH hammer or core barrel is added; for loose sand a casing oscillator keeps the bore stable. Tooling is chosen against your site investigation.

Diesel powertrains can be calibrated to Euro II or Euro V for the destination market. We ship the full export document set and localized operator manuals, and quote the correct emission level after you confirm the destination country.

Standard fuel-fired models ship within 30–60 working days after deposit; customized masts and tooling add time. The rig carries a 12-month warranty with spare-parts kits and 48-hour technical support from the export engineering team.
