The Bumdrill is a heavy duty foundation
drill that is mounted on an excavator.
The attachment utilizes the excavator
hydraulic system for its operation.
It's ideally suited for digging foundation
holes in confined areas, where overhead
clearance is limited or where site conditions
require a drill rig with reach or the
characteristics of an excavator carrier.
The Bumdrill retains the advantages
of a track mounted excavator and adds
capability of a highly productive drill
rig.
The Bumdrill machine is normally comprised
of Winch Head, Rotary Drive, Rotary
Motors, Kelly Housing, Kelly Bars, Crowd
Cylinder, Service Winch, Main Winch,
Tilt Cylinder, Pivot Point Connector
and Drilling Tools.
