Determining the adjustment range for belt tensioning

The adjustment range on the conveyor must be at least 1,5% of the total length of the belt. Hence,for a belt with a total length of 10 m, the tensioning system of the conveyor must at least have an adjustment range of 75 mm.

 

Determining the length of a belt

La longueur d'une bande doit être mesurée avec le système de tension sorti au 1/3. Pour passer la bande, il faudra rentrer les tendeurs entièrement. Il restera ensuite 2/3 de course de réglage pour tendre la bande.
