B31
The B-31 is a compact hydraulic drill with applications in geotechnical, foundation exploration, mineral and aggregate prospecting, post-hole auguring and shallow surface coring. An optional conversion kit for concrete & asphalt coring up to 24 inches [610 mm] OD size is available.
The hydraulic rotary head drive
allows a safe operation at full capacity by reducing
vibration and cushioning the drive train against
shock loads. The enclosed low-maintenance hydraulic
drive system keeps dirt out to help minimize wear.
The B-31’s compact size permits
mounting on a variety of carriers to provide go-anywhere
versatility. Truck, tractor and trailer mounts are
the most common setups.
The B-31 can be powered either
from a carrier engine or a dedicated drill engine.
