QLX 50/55 - The Latest in High Performance DTH Hammers
Secoroc QLX 50/55 hammer at Roschen and Atlas Copco Secoroc, we
keep looking for new ways of improving our customers' productivity.
That’s why we have taken the best of the QL design, thrown in a few
new ideas, and created the Secoroc QLX 50 and QLX 55 down the hole
hammers.
QLX 50 and QLX 55 are primarily deep hole hammers, but have also
proven to be high performance hammers for other applications.
These new 5" hammers offer 20% more all-around performance than the
QL hammers and better water-logged deep hole drilling capacity than
its predecessor, the TD 50 hammer. They are benchmarks with the
highest rate of penetration (ROP) and reliability that are a cut
above the rest, thanks to solutions such as the new e-kit making
servicing easier and quicker to execute. The QLX 55 has thicker
heavy duty (HD) casing for longer service life when drilling in
abrasive rock formations.
The QLX 50 and QLX 55 have been stringently field tested in the USA
and Sweden prior to launch. They have proven outstanding in water
well, geothermal drilling, and other applications thanks to the Air
Select feature that enables the QLX to match a variety of air
packages while utilizing the excess air for hammer power.
