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

Round conveyors are essential and are often crucial in a complex system with several lines. Especially when it comes to high belt speeds, varying speeds and start/stops you need a high quality round conveyor. In this segment the R series of Kramer & Duyvis is at his best! Kramer & Duyvis produce these round conveyors since the 60’s and still this is the most proven round conveyor in this segment.

Kramer & Duyvis delivers these curves with a conical roller Ø 50 mm to 350 mm and belt widths from 200 mm to 2800 mm. There are no restrictions in the radius of the round conveyor, but there are of course technical constraints we are facing. The angle and radius is always custom. it is also possible to create different heights in the bend which creates a Helix model (type S).

The R-series of Kramer & Duyvis can have a basic of steel (coated) or stainless steel. The R-series is unique in its kind. There are no standards, so the customer has the freedom to implement all their wishes.
