Product Description

DTH hammer is a percussion system driving a piston inside hammer body with up and donw motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

Sansung company makes and supplies the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining, construction and water well industries. Sansung 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.

Drill and blast engineers and water well contractors trust Sansung's DTH equipment because of the precision engineering and high standards of drilling efficiency built into each of our hammers and bits.

Sansung hammers are flexible, and designed to work with various industry-standard shank designs and a wide range of standard size hammers. Whatever your application, Sansung has the solution to match your requirements.

Advantages:

- Advanced hammer designs with high power and air efficiency increases productivity

- Tailored product offering covers all your applications and conditions

- Easy service and maintenance designs reduces machine downtime

- Generic and proprietary shank options give you flexibility and reliability
