ROTARY TOP HEAD DRIVES
Holte Manufacturing has been modifying existing drive heads for many years. We can turn your Kelly drive system, providing it has a large spindle opening, into a fully functional reverse circulation system, complete with air inlet, pinch valves for grout through technology and cuttings discharge.
We have modified Bauer, Casagrande, Soilmec, ABI and many other brand machines into fully functional RC drilling rigs making them truly the most versatile drill rigs on the market today capable of drilling large foundation holes into hard rock formations where other systems simply can’t go.
These modifications will open new doors and will keep you ahead of the competition as the demand for larger drilled foundation holes into rock grows and spread footings any longer satisfy seismic requirements.
Contact us today at Holte and find out how we can help you turning your rig into a more capable machine at a minimal cost.
You’ll be glad you did.
