Conveyor Belt Maintenance & Common Conveyor

Conveyor belts rely on a precise balance of tension to work correctly. If there is too much tension or too little, things begin to go awry, and the belt can slip. Specifically, if the head pulley breaks down or even becomes overly worn, there will no longer be enough tension to keep the belt from slipping around.
