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.

Application conditions

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

Environment: Dry to humid and clean to very polluting

Load: Max. 1500 kg (divided depending on version)

Speed: Max. 200 m/min (in the outer radius)

Roller diameter: Conical Ø50 - Ø350 mm

Kramer & Duyvis supplies these curved conveyors with a conical roller from Ø 50 mm to Ø 350 mm and the belt widths vary from 200 mm to 2800 mm. There are no restrictions on the radius of the curve, but there are of course technical limitations that we have to deal with. The angle and radius is always customer specific. It is also possible to create a difference in height in the bend, creating a Helix version (Type S).

The R-series from Kramer & Duyvis can be produced in steel (coated in your desired RAL color) or in stainless steel. The R-series is one of a kind. There are no standards, which means that you have complete freedom to implement your wishes.
