Higher turnover thanks to zero downtime: shaft changes in minutes, right on the building site
The patented quick-change system on MB Crusher bucket separators saves on costly workshop visits and long set-up times. Instead of taking the bucket out of service for days on end, a single person can change the screening and crushing shafts in a matter of minutes, right on site – the appropriate tool is carried directly on the bucket.
Once the side cover has been removed, the rotors can be easily taken out and immediately adapted to a new material (e.g. from damp soil to gypsum or construction rubble). For you, this means: maximum flexibility, no machine downtime and the ability to handle completely different jobs one after the other using just a single bucket.
