6.4 Walking belt tension
The walking belt can be tightened by means of the two outmost socket screws placed on the
feed at the end of the frame:
First decrease the tension on the walking belt fully by turning both tightener socket screws
anti-clockwise. To prevent from unnecessary disturbance of the walking belt alignment the
number of turns should be kept equal on both socket screws. The walking belt tension can be
adjusted according to procedure 1 or 2:
1. When the walking belt is quit slack, start the walking belt at minimum speed. Turn both
tightener socket screws an equal number of turns clockwise until the walking belt, when it is
slowed down with your feet, just stops slipping on the driven roller. Then give both tightener
socket screws 2.5 additional turns.
2. When the walking belt is quit slack, put two marks (on adhesive tape) in the middle of the
walking belt with 1000 mm. distance between them. Turn both tightener socket screws an
equal number of turns clockwise until the distance between the two marks is 1003 mm (the
walking belt is stretched 3 mm. over a length of 1000 mm.). After each adjustment of the
walking belt tension the alignment of the belt should be checked.
Caution: Do not tighten the belt to much. This will shorten the service life of the walking belt
and it will make the drive motor run unnecessary heavy.
