Integrated Hydraulic Crawler Mounted DTH Drilling Rig

When drilling or blasting in mines or quarries, rough terrain, high fuel costs, and equipment downtime can slow your projects. The RCZ421T is designed to provide a more efficient, reliable, and adaptable solution.

Why Choose Our RCZ421T Integrated Drilling Rig?

✔ Power & Function Integration

With our trusted Yuchai YC6J190 diesel engine, you get reliable power for both the 12m³/min, 15bar screw air compressor and the hydraulic system. This setup allows you to drill hole diameters of φ80–115mm with ease. Our standard dry dust removal system keeps your jobsite cleaner and compliant with environmental standards.

✔ Save More on Energy & Maintenance

We know fuel costs and downtime hurt your business. That's why we use a single power source drive system - one engine powers both the compressor and the hydraulics. This smart design helps you cut fuel consumption by up to 35% and extend your maintenance cycle by 50%, so you spend less time repairing and more time drilling.

✔ Built to Last with Industrial-Grade Components

We use ISO 9001-certified European hydraulic components, engineered to withstand high-pressure, heavy-duty work. You'll experience fewer breakdowns and more consistent performance.

✔ Ready for Any Terrain

Quarries and mines aren't easy places to work - but the RCZ421T adapts. Our dual-speed hydraulic crawler system lets you travel at up to 3km/h and climb slopes up to 25°. With a 3500N·m torque slewing mechanism, powered by a high-torque cycloid motor and planetary gearbox, you'll reduce the risk of drill jamming and keep your project on track.

✔ Smarter, Connected Operation

The integrated on-board compressor plus IoT monitoring module lets you check equipment status remotely, get early fault warnings, and collect real-time operation data. If you're managing multiple rigs, you'll appreciate how easy it is to centralize and optimize operations.

Our customers often tell us: when they choose the RCZ421T, they don't just get a machine - they gain a reliable partner that supports their drilling projects day after day.
