Easy and fast assembling
( 2 cross pieces to be bolted to the conveyors framework).
has always to be set up between 2 idler stations having the same trough angle, ( festoon type or 5 rollers stations ) when troughing angles are more than 45°
These idlers provide trough shaping of the belt respecting the transition zone and limiting strains.
When the transition zone is short, troughing angle must be limited to the same value as the first station located in the impact zone.
