Atlas Copco upgrades FlexiROC T15 R drill rig with unique rollover feed system
One of the smallest radio controlled drill rigs in the Atlas Copco range has now become one of the most versatile thanks to an innovative rollover feed system.
Atlas Copco’s FlexiROC T15 R drill rig, which is used for a wide variety
of small-scale drilling jobs such as preparing building sites and
trenching, has now considerably expanded its field of application.
The reason is a completely new boom concept which enables the rig to
switch from downwards drilling to upwards drilling in one easy
operation. This facility on the FlexiROC T15 R is extremely easy to use.
All the operator has to do is put the rig into tramming mode, remove a
locking pin, push the feed round 180 degrees, replace the pin and start
drilling once again.
This procedure, called re-pinning, takes just a few minutes and enables
the rig to be used in eight different configurations, including toe-hole
drilling at various angles, upwards or downwards. The switch is also
safe to carry out as the feed beam is in a resting position while the
re-pinning is being done.
“The FlexiROC T15 R is now even more valuable to have in the fleet,”
says Erik Ahlström, Product Responsible Service Engineer at Atlas Copco
Surface Drilling Equipment. “With a great vertical coverage area of 18
square meters it can go from drilling vertical holes to horizontal
toe-holes and then to upward drilling for, for example, rock
reinforcement all from the same set-up.”
The rig is also extremely economical to run thanks to its high-torque
Cummins B3.3 (Naturally Aspirated) diesel engine. During tests in Sweden
with 47 % active drill time drilling 45 mm holes in hard granite, the
recorded fuel consumption was less than 5.7 litres per hour.
