7.7.2.5 Specific travelling resistance
VULKOLLAN wheels
VULKOLLAN wheels are particularly suitable for conveyors and drives for loads up to 10 t or even
more.
• For the determination of the travelling resistance the following table can be included:
• Usually the consideration of the rolling friction is sufficient with regard to determining the trav-
elling resistance. Only for applications featuring frequent start-stop processes, the travelling re-
sistance increases due to the starting resistance.

• If the specific travelling resistance is calculated via the "travelling resistance" calculator, the
values for wheel diameter and angle of tilt must be entered in the calculator for this purpose.
