DOWN-THE-HOLE HAMMERS
DTH(Down the Hole) hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.
Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.
Roschen offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.
Roschen DTH hammers transmit intensive impact energy with low energy loss. This results in good rock breakage, high penetration rates and high productivity. The equipment is designed to give optimal hole quality, reliability, and long service life, as well as the best blasting results and low total operation cost.
Roschen hammers are flexible, and designed to work with various industry-standard shank designs and a wide range of standard size hammers. Whatever your application, Roschen has the solution to match your requirements.
Advantages:
1. Advanced hammer designs with high power and air efficiency increases productivity
2. Tailored product offering covers all your applications and conditions
