Product Overview
The YTR406DH cuts 2500 mm of maximum drilling diameter at up to 65/100 m depth, with 406 kN·m of rotary torque and 331 kW on the deck. It is specified where pile and diaphragm-wall work needs a machine that holds torque at depth rather than a bigger boom.

Performance Feature
Drills 2500 mm diameter holes, which covers most production pile and diaphragm-wall specifications.
406 kN·m of rotary torque is held at depth without stalling in gravels and weathered rock.
Depth capability of 65/100 m lets the rig finish a full section between rod changes.
331 kW of installed power is matched to winch, crowd and rotary loads so the engine never hunts on the hardest metres.

About the YTR406DH Rotary Drilling Rig
Yutong's YTR406DH is a the proven Yutong 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 YTR406DH 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 YTR406DH 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.
Diaphragm wall and hybrid tooling
Diaphragm wall programmes put the YTR406DH to work with trench cutters or grab tooling, where torque control and crowd accuracy matter more than raw diameter. The rig's hydraulic response keeps the tool square in the trench, and the winch manages the heavy tool string without hunting. Contractors on deep excavation jobs run this spec where the same rig has to switch between diaphragm wall and pile work across the season.
Frequently Asked Questions
What is the maximum drilling depth of the YTR406DH 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 YTR406DH 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.
