Product Overview
The YTR300Dmax cuts 2500 mm of maximum drilling diameter at up to 56/84 m depth, with 320 kN·m of rotary torque and 294 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.
320 kN·m of rotary torque is held at depth without stalling in gravels and weathered rock.
Depth capability of 56/84 m lets the rig finish a full section between rod changes.
294 kW of installed power is matched to winch, crowd and rotary loads so the engine never hunts on the hardest metres.

About the YTR300Dmax Rotary Drilling Rig
Yutong's YTR300Dmax 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 YTR300Dmax 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
For urban and low-emission sites, the YTR300Dmax drills the rated mm diameter at the rated kN·m of torque and uses the rated kW of installed power, with a driveline matched so the rotary head never hunts on the hardest metres — which holds fuel and emission numbers on restricted sites. The power curve stays flat across the working range so the rotary, winch and crowd loads never compete.
Production piling in stiff clays
The YTR300Dmax is typically tendered for production piling where the ground profile is stiff clay over weathered rock. The rotary drive holds the tool in clays without slowing the head, and the crowd system keeps penetration on schedule through the stiffer horizons. Piling contractors on this duty usually match the rig with a temporary casing table, because the bore sizes the YTR300Dmax is rated for need casing support through the upper clay until the tool seats in the rock socket.
Frequently Asked Questions
What is the maximum drilling depth of the YTR300Dmax 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 YTR300Dmax 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.
