11.3 Conveyor Settings
11.3.1 Setting the Belt Tension
11-8: Measuring and setting the belt tension for the width adjustment
ATTENTION: Press the EMERGENCY STOP!
Before performing adjustment work you must ensure that the lifting table has been secured
against movement!
NOTE:
The belt tension is measured at the point where the distance between the two deflection pulleys
is the greatest.
11-7: Measuring and setting the tension of the conveyor toothed belt
Legend
1. Deflection pulley with slot
2. Measuring point of the belt tension measuring
device (strand center )
Each conveyor section contains a deflection pulley
that can be moved. Loosen the fixing screw (1)
and move this deflection pulley in order to set the
belt tension for the associated conveyor belt (2).
The belt tension is measured at the longest point
between two idler pulleys.

3 Adjustment unit 1.2 and 3 T Transport direction
11-9: Width adjustment motor
The belt is tensioned is set by means of cams on
the idler pulleys. The idler pulleys are located on
the left and right of the motor.
Legend
1. Loosen the cam shaft on the idler pulley and
set the belt tension.
NOTE:
The modular conveyor uses different belt lengths. The different belt tensions between the
conveyor lanes are due to the different arrangement of hexagonal shafts and deflection pulleys.
