Loading equipment
Belt tension
The belt tension of the loading belt and the
discharge conveyor is to be checked daily. If the
belt sags too far, the tension must be increased.
In the first weeks of operation, the belt will stretch
excessively (permanent and elastic stretching).
Therefore, it is necessary to tighten the belt
repeatedly during this time.
The sag of the belt of the primary conveyor should
be somewhat greater than the sag of the
discharge conveyor.
To increase the tension:
- Loosen the lock nuts (1) on both sides of the
tightening equipment.
- Increase the tension evenly on both sides
using a fork wrench on the adjusting nuts (2).
- Tighten the lock nuts (1) again after the
adjustment.
The tension setting of the loading belt and the
discharge conveyor is basically the same.
If the belt runs asymmetrically, tighten the right
spindle or loosen the left spindle if the belt runs
towards the right or vice-versa.

Also visually check the belts, conveyor belt
rollers and support rings for damage or wear
controls.
Worn support rings can be replaced in sets.
Regularly remove material encrustations on
the rollers.
Regularly check the screwed connections.
During all work on the loading and
discharge conveyors, ensure that the belt
drive cannot be started!
