HEX-Mounted Rock Drills from Junttan
Junttan Oy, a Finnish company, presented
its line of RockDrills designed to be
mounted on hydraulic excavators. The
RockDrill line, which includes models
capable of drilling hole diameters ranging
from 30 to 127 mm, is topped by the flagship
model 45A/51A. The 45A, designed
for both utility drilling as well as production
drilling, is suitable for mounting on
excavators weighing more than 30 tons
and has a hole diameter capability of 51-
102 mm. The 51A is intended specifically
for open pit mine duty and has a diameter
range of 89-127 mm. An optional rod
changer allows drilling to a depth of 29 m.
All units are equipped with the AutoDrill
automatic drilling system, which allows
direction of drilling to be controlled from
the cab and which automatically reacts to
changes in the rock. The AutoDrill system
also can display angle and depth of hole
and the drills can be equipped with a
video monitoring camera for better operator
visibility.
