EXCAVATOR
MOUNTED DRILL
Dawson's excavator mounted drilling machine has been designed to fit via an
adaptor plate to the stick arm of an excavator and runs via the flow and return
lines that normally supply the bucket or a double acting breaker circuit .
There are five models to choose from starting at 17.5kNm up to 48.5kNm that
cover a wide range of applications from drilling precise holes in many varied
ground conditions, subject to the auger/drill bit, through to stirring the ground
prior to using a Dawson EMV vibro piling machine.
By selecting the correct drill bit combined with the down-crowd force of the
excavator the EMD will make light work of the most demanding conditions.
Another benefit of the EMD is that because its mounted on your excavator
you can drill vertical holes, anywhere the excavator goes. It's ideal for drilling
over casings, on railway embankments, under bridges, or near power lines, +
anywhere with low headroom constraints.
