Quick-Change Block System maximizes uptime.
March 31, 2014 -
For surface mining and trenching machines, no-weld QC42 Quick Change Block System cuts time needed to change block from machine base from 60–90 min down to 10–15 min. System features 1070 spring steel retainer that provides added safety feature to keep unit together when not fully engaged from tapered press fit. Rubber bumper stops keep block from over-locking, while hardfaced block face ensures optimal conical rotation and minimizes wear.

New design features increase reliability
Kennametal´s QC42 Quick Change Block System cuts block change time from 60 to 90 minutes down to 10 to 15 minutes, dramatically improving machine uptime.
With the right tools for the right application, attacking even the most difficult cutting conditions is made easier. With many mines moving to a »no blasting, no drilling» mode, surface miner machines are encountering more severe cutting work. With a new no-welding modular block system, Kennametal´s QC42 Quick Change Block System cuts the time needed to change the block from the machine base from 60 to 90 minutes down to 10 to 15 minutes, dramatically improving machine uptime.
The QC42 system incorporates many new design features to make it more productive and reliable:
-a new 1070 spring steel retainer provides an added safety feature to keep the unit together when not fully engaged from a tapered press fit.
-rubber bumper stops keep the block from over-locking.
-a newly designed hardfaced block face ensures better conical rotation and minimizes wear.
For surface mining and trenching machines, the new QC42 Quick Change Block system reduces tool-change time and features a no-weld design for a safer work environment, taking machine uptime and productivity to a whole new level.
