About the YTR306HE Range-Extended Electric Rotary Drilling Rig
Yutong's YTR306HE 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 YTR306HE 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 YTR306HE is quoted with tooling matched to the contract strata: the rated mm diameter take augers, buckets, core barrels or a DTH hammer as the ground dictates, and the rated kN·m of torque with the rated kW drive the tool at the rate the soil report expects. The mast and rod handling are sized so tool changes stay quick on multi-strata sites.
Mixed-diameter urban foundation
The YTR306HE covers the mixed-diameter foundation work that urban contractors see across a season: smaller bored piles for commercial buildings and larger bores for basement structures. The electric rotary keeps the torque band across the range, and the rod handling accepts the tool changes the mixed programme demands. The HE power package holds the site's emission and noise conditions while the diameter envelope keeps the rig on site longer between mobilisations.
Frequently Asked Questions
What is the maximum drilling depth of the YTR306HE 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 YTR306HE 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.
