How are belts tensioned?

Exerted tension depends on the type of belt used (from 0.5% to 8% for Mafdel belts – see the catalogue for recommendations).

There are two ways to apply tension to a belt:

  • The conveyor is equipped with a suitable tensioning system: In this case, the tensioner must be set to the minimum, install the belt and adjust the tensioner to apply the belt tension.
  • The conveyor is not equipped with a tensioning system, or it is insufficient: In this case, you must use pre-tensioning tools comprising a winch and two tightening jaws, which will enable you to pull the belt ends together and then apply the welding process.

If the belt is reinforced, you must take care not to apply excessive force, which could destroy the reinforcement.
