Hydraulic Rock Drills with External Flushing Head
Atlas Copco has released two new versions
of its COP 1838 hydraulic rock
drill—the COP 1838MUX and COP
1838HUX—intended for use in underground
long-hole drilling. The new versions
feature an external flushing head
combined with the extractor unit to
improve serviceability; this is now standard
on all Atlas Copco top hammer rock
drills that have an extractor unit. An
upgrade kit with external flushing head
will be available for older versions. The
external flushing head provides improved
serviceability when changing flush seals
because the extractor unit does not have
to be removed—so there is no need to retorque
the side bolts afterward and fewer
tools are needed for drill operation. The
head also reduces the risk of water intrusion
on the rock drill which should
increase the life of essential components.
