Rockmore’s new DTH hammer drill

Rockmore International is adding its new ROK 550T drill to its T Series DTH hammer line. The T Series DTH hammers are TUBELESS and use drill bits featuring industry standard shank connections without the embedded plastic blow tube/foot valve. The firm’s first T Series DTH model was the ROK 600T, a 152mm class model that uses a tubeless QL6/QL60 bit shank. The company then expanded the T Series with the ROK 60T-360T hammers that use the IR 360 bit shank without the blow tube/foot valve. And Rockmore is now

Rockmore’s new DTH hammer drill offers high performance

5087 Rockmore International is adding its new ROK 550T drill to its T Series DTH hammer line. The T Series DTH hammers are TUBELESS and use drill bits featuring industry standard shank connections without the embedded plastic blow tube/foot valve.

The firm’s first T Series DTH model was the ROK 600T, a 152mm class model that uses a tubeless QL6/QL60 bit shank. The company then expanded the T Series with the ROK 60T-360T hammers that use the IR 360 bit shank without the blow tube/foot valve. And Rockmore is now extending the T series with its 127mm class ROK 550T, which uses the industry standard QL5/QL50 bit shank, but with the blow tube/foot valve removed.  With high performance drilling characteristics rated for drilling 140-152mmdiameter holes, the ROK 550T is suitable for blast-hole applications in extraction and construction markets.

As with all Rockmore DTH hammers, the new ROK 550T is said to take advantage of the firm’s patented SonicFlow technology, which optimises airflow by simplifying and streamlining the air paths to minimize back flow and turbulence, delivering more energy to the piston. Field testing of the SonicFlow design was determined to result in faster penetration rates and greater overall DTH hammer efficiency.

    Internationally, airports are being upgraded and expanded to increase capacity and safety – Mike Woof writes. All around the world, airports are being expanded and upgraded, both to cope with massive increases in passenger numbers and also to handle larger aircraft. Runways have to be rebuilt with stronger structures and surfaces to handle greater air traffic volumes as well as increased loads from larger aeroplanes. Building airport runways, however, poses many challenges for construction crews. Paving qua

    Will increased ADT load capacity provide a suitable solution to increasing aggregate and earthmoving haulage needs? Mike Woof reports The rule of thumb with off-highway machinery is that for bulk operations, larger equipment can deliver economies of scale, with bigger payloads allowing a better cost/tonne. Heavier machines may be less versatile than more compact units, so a type of equipment that retains its versatility as it is scaled up in size can offer major benefits. For the articulated dumptruc
