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.
