About the YTR266HE Range-Extended Electric Rotary Drilling Rig
Yutong's YTR266HE is a range-extended electric driveline rig engineered around the rated mm of diameter and the rated kN·m of torque, with the rated kW driving winch, crowd and rotary — the numbers a piling contractor compares against the soil report before mobilising.
The rig is factory-tested at rated torque and depth: mast deflection, rotary drive temperature and winch hold are checked against the spec, and the rod-handling sequence is validated so the crew keeps cycle times predictable on site.
Choosing the YTR266HE starts with the pile and diaphragm-wall programme: Yutong sizes diameter, depth and torque from the drawings, then supports the rig with spare parts, operator training and field service across export markets.

View DetailsEngineering & Application Notes
The YTR266HE is set up so rod changes do not pace the job: the mast, rod string and handling sequence are matched for the rated mm diameter work, and the rated kN·m of torque with the rated kW keeps the rotary head working while the crew services the tooling. Cycle time per bore is what contractors compare, and the rig is built around holding that cycle on production piling and diaphragm-wall programmes.
Ramped piling on sloping sites
On ramped and sloping sites the YTR266HE is chosen for the mast and levelling system that keeps the bore vertical on grades. The electric drive holds torque without the engine pitching on the slope, and the crowd system works the tool on the angle without drift. Piling contractors on hillside residential and viaduct approach work run this class where the mast compensation is the number that decides foundation quality.
Frequently Asked Questions
What is the maximum drilling depth of the YTR266HE Range-Extended Electric Rotary Drilling Rig?
The drilling depth depends on the specific configuration and mast length selected. Yutong rotary drilling rigs are available in configurations ranging from approximately 30 meters for small urban models to over 100 meters for large deep-pile machines. Contact our engineering team for exact specifications for your project requirements.
What ground conditions can this rig handle?
Yutong rotary drilling rigs are designed to handle a wide range of strata including clay, sand, silt, gravel, and moderately weathered rock. The appropriate drilling tool (auger, bucket, core barrel, or DTH hammer) should be selected based on the specific ground conditions encountered at your site.
Is the YTR266HE Range-Extended Electric Rotary Drilling Rig suitable for urban construction?
Yes, especially the electric and range-extended models. These produce zero local emissions and significantly lower noise levels compared to diesel rigs, making them ideal for urban core projects near residential areas, hospitals, and schools where environmental regulations are strict.
What is the lead time for delivery?
Standard models typically have a lead time of 30-60 days from order confirmation, depending on configuration and shipping destination. Customized options and special tooling may require additional time. We export to over 60 countries worldwide with reliable logistics partners.
What after-sales support does Yutong provide?
Yutong provides comprehensive after-sales support including spare parts supply, operator training, and remote technical assistance. Our global service network covers major markets, and we can dispatch engineers to project sites for commissioning and maintenance when required.
Can the rig be customized for specific project requirements?
Absolutely. Yutong offers customization options including extended masts, specialized drilling tools, cabin configurations, and telematics systems. Our engineering team works directly with customers to match the machine to specific pile diameters, depths, and ground conditions.
Does Yutong export to my country?
Yutong Heavy Industries exports construction machinery to over 60 countries across Asia, Africa, the Middle East, South America, and Eastern Europe. We have established dealer and service networks in major markets. Contact us to confirm availability in your region.
