Automatic Integrated Hydraulic DTH Blast Hole Drilling Rig For Mining

Product Description

The RCZ421T is a high-performance DTH surface drill rig designed for ore mining and quarry blasthole drilling, capable of drilling holes φ80-115mm with a 12m³/min, 15bar air compressor and dry dust collector. Equipped with a Yuchai YC6J190 power pack, it features an integrated single-engine system that drives both the air compressor and hydraulic system, reducing fuel consumption by 35% and maintenance costs by 50% compared to traditional rigs. Its robust design includes globally renowned hydraulic components, ensuring reliability and low upkeep.

With a two-speed hydraulic tramming mechanism, the RCZ421T delivers good off-road mobility, while its heavy-duty rotation unit provides smooth, high-torque drilling with minimized jamming. The two-stage dry dust collector enhances environmental protection and productivity, and the integrated onboard air compressor simplifies fleet management for long-distance operations. A cost-effective, high-efficiency solution for modern mining and quarrying!
