Description
The SMC-DTH-628 Separated Crawler-Mounted Surface Hydraulic Down-the-Hole Drill Rig is a cost-effective, high-performance solution engineered for drilling blast holes in open-pit mining, metallurgy, building materials, railways, hydropower, national defense, and underwater reef blasting projects. Designed for affordability without compromising performance, it features hydraulic-driven crawler movement, rotary drilling, feed, lifting compensation, and leveling functions. Impact drilling and flushing are powered by compressed air, while a wet dust collector and high-pressure air system ensure clean operation. With globally sourced components and power-load adaptation systems, the SMC-DTH-628 delivers optimal efficiency, reduced energy consumption, and reliable performance in demanding environments.
