Challenge
 

De oude loopkat van de ertskraan 123 was aan vervanging toe. Corus had voor ogen om door middel van gewichtsbesparing de hijscapaciteit en daarmee ook de productie te verhogen. Het doel was om van de 9 ton zware kat 1,5 tot 2 ton te besparen, met het originele ontwerp als uitgangspunt. De uiteindelijke besparing kwam op 1,75 ton.

 

Solution

UIT behandeling van de kritische lassen in de constructie ter verhoging van de weerstand tegen vermoeiingsbelasting.

 

Benefits

 

In vergelijking met de het oude ontwerp van de loopkat is er door de UIT behandelingen een grote besparing in gewicht bewerkstelligd, waardoor de productiviteit van de kraan aanzienlijk verhoogd is.
