If we put more in, you get more out
Caterpillar Propulsion has a simple dimensioning principle to ensure maximum uptime: We use more material. Our propellers are built to last, holding against stress and fatigue even in the most extreme conditions. And with costly, unplanned stops kept to a minimum.
Lighter propellers and smaller shafts would be cheaper to manufacture but we will not pass on the far larger cost to the customer of standstills and lost revenue.
