About the YTR506HE Range-Extended Electric Rotary Drilling Rig
The YTR506HE rotary drilling rig uses a range-extended electric driveline and is rated for the rated mm of diameter with the rated kN·m of rotary torque on the rated kW of installed power. Yutong sizes the rotary drive, crowd and winch together so the rig holds torque at depth through gravels and weathered rock rather than trading penetration for boom size.
The mast, rod handling and winch are built as a matched system: rod changes are sequenced so the crew keeps penetration on schedule, and the crowd and rotary drive are protected against stall loads in mixed ground. Load tests and torque calibration are run on every unit before it leaves the factory.
Selecting the YTR506HE comes down to bore diameter, depth and the ground profile on site. Yutong works from the tender drawings to confirm diameter, depth and torque, then matches the rig, rods and tooling to the contract, with spare parts and field support available through the global service network.

View DetailsEngineering & Application Notes
On deep-pile and diaphragm-wall programmes, the YTR506HE works to the rated mm diameter with the rated kN·m of torque and the rated kW installed, and the power pack keeps winch and crowd capacity available at the same time as rotary drive. The rig is specified where bore depth, casing length and ground stiffness make torque-at-depth the deciding number.
Deep urban pile programme
On deep urban pile programmes the YTR506HE keeps the electric drive advantage at the larger diameter band: the rotary torque and crowd are available at depth without the diesel plant running, and the rig fits the restricted compound layouts of city sites. The mast and rod handling are matched to the deeper rod strings this class runs, and the electric power package keeps the noise and exhaust profiles inside the site's permit conditions.
Frequently Asked Questions
What is the maximum drilling depth of the YTR506HE 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 YTR506HE 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.
