About the YTR486HE Range-Extended Electric Rotary Drilling Rig
The YTR486HE 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 YTR486HE 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
The YTR486HE is built to mobilise between pads: the rated mm diameter in a mast and rod package that fits the site access, with the rated kN·m of torque and the rated kW installed power on a carrier that keeps transport within legal limits. Contractors use the rig where moving between bore positions is as important as the drilling rate itself.
Pile caps and near-surface rock
Where pile caps sit in near-surface rock, the YTR486HE is tendered for the socketing work: the rotary drives the core barrel and socketing tool at the diameter the pile cap requires, and the crowd feeds the tool at the penetration rate the rock allows. The electric package keeps the rig working inside the excavation footprint, and the winch handles the socketing tool string at the depth the rock socket reaches.
Frequently Asked Questions
What is the maximum drilling depth of the YTR486HE 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 YTR486HE 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.
