DTH drilling rigs are a new generation DTH drilling rig designed for medium to large quarries and contractors. These devices fit perfectly with the 5-inch DTH impactor, which gives it unique productivity and minimizes fuel consumption and operating costs. Extremely high availability, efficient drilling and unobstructed component layout are standard. We believe the Leopard™ range of drills can take on any task, including production drilling, quarry/mine development and slope control.
DTH drilling rig is a diesel-powered self-propelled crawler intelligent DTH drilling rig designed to meet the needs of large-scale production hole applications in surface mining and large quarry applications. The rock drilling equipment features an operator's cab, fixed boom beam, dry dust collector, rod changer, and features the most advanced design and layout available today.
