Round conveyor Type R

Curved conveyors Type R

The experience of the market leader in conical roller round conveyors!

Round conveyors are essential and are often crucial in a complex system with several lines. Certainly when it comes to high belt speeds, varying speeds and or start stops, it comes down to the fact that you as a user want as little maintenance as possible on your round conveyor. The R series from Kramer & Duyvis excels in this segment! Kramer & Duyvis has been building these curved conveyors since the 1960s and this is still the most proven curve in its segment.

In order to use the curved conveyor Type R, your application must meet the following conditions in order to guarantee a long service life:

The angle and radius is always customer specific.
