DRILL & ADAPTER SUBS

Roschen's extensive range of lengths, diameters, tool joint and thread configurations allows for individual  customization of drill and adapter subs to suit all of our client’s requirements.



DECK BUSHING


Light Weight Deck Bushing - The Safer Option


Light weight deck bushes are made from a mild steel top plate, sleeve and bottom plate, which are welded together and then injected with polyurethane.

We are able to achieve about 50%-70% weight reduction on these deck bushes, decreasing the possibility of manual handling injuries.


Static & Rotary Deck Bushing

Roschen offer both static, non-rotating deck bushing suited to DTH drilling and rotary deck bushing with a scope of double and triple race bearings.



BREAKOUT BASKETS

Roschen designs and manufactures a complete line of breakout baskets to suit both rotary and DTH bits for a broad range of drill rigs.



LIFTERS


Deck Bush Lifters

Roschen deck bush lifters take the hard work out of bit changes. Our products are easy to use and light weight to ensure bit changes are carried out safely and efficiently. The handle has been load tested and certified as a lifting point.


Lifting Bails

Roschen has a range of heavy duty steel and light weight aluminium lifting bails to suit BECO and API thread types. All lifting bails contain a swivel to eliminate undoing of the thread on the lifting eye and are load tested and certified to American standards.
