“In this project we worked very closely with SSAB‘s wear and manufacturing experts. We used their knowledge to establish the best way to bend and weld the drums. This cooperation has been very valuable when developing our new oscillating rollers,” says Andreas Lager at Dynapac.
When the production techniques were in place, a couple of full-scale prototypes were constructed and put into action in regular field tests.
“Our prototype rollers were monitored for up to 1,000 hours of tough operation and the belt drive on the oscillating drums showed hardly any wear at all. It will be really interesting to see how the rollers perform in the field,” Lager says.
