QLX - The Latest in High Performance Water Well and Mining DTH Hammers

QLX 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 from the TD hammer, added the best of the QL design, thrown in a few new ideas, and created the Secoroc QLX 60 and QLX 65 down the hole hammers.
These new 6” hammers offer 20% more all-around performance than QL hammers and better water-logged deep hole drilling capacity than its predecessor, the TD 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 60 and QLX 65 have been stringently field tested, drilling almost 750,000 feet prior to the launch. They have proven outstanding in mining and water well drilling 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.

 

 

The Secoroc QLX 60 and QLX 65 are the first of a completely new range of reliable high performers with the latest technology.
