Cross conveyor belt maintenance
DANgER
Danger to life exists through moving or rotating parts
Carry out maintenance works on the machine only
when
•
it has been parked securely on level, firm
ground,
•
it has been secured against rolling, and
•
the tractor engine is turned off and the pto
shaft is stationary.
•
All moving or rotating parts have come to a
standstill. (Hearing test!)
•
The tractor's ignition key has been removed.
Danger to life exists when under the machine.
•
Adequately support the sections you will be
under.
1. Check the belt run every 5, 10, 20 hours. Then
every 20 hours thereafter.
• Belt must not become tarnished on the edges.
• Belt must be centred on both rollers.
• Belt must run in both guide rails
Possible causes for high belt wear:
- Belt tension to loose
- Belt not running centred
- Increased contamination on the deflection rollers
Set belt tension

1. Tension the belt so that it does not slip.
a. Mark 3000 mm on the belt (see the sketch)
3000 mm
b. Tension the belt using the tensioning lever (S) until
the distance between the markings has reached
3012 - 3015 mm.
c. Secure the tensioning lever by means of the linchpin
(V).
Adjust the belt position
Adjust the position of the rollers by moving the tensioning
block (S).
- The belt runs centrally on the rollers and does not
rub against the machine.
- Belt runs centrally in the guide grooves and does
not work outwards
- Carry out a 5-minute trial run
Check the belt tension and position in both running
directions.
Adjust the feed plate:

The distance between the conveyor belt and the feed plates
is adjusted with the screws (1). The distance between the
plate and the conveyor belt is at least 5 mm. This distance
also applies to all plates on the deflection rollers. There is
a total of 5 screws on these plates (2).
TIP
Set the feed plate correctly from the beginning.
Doing so prevents blockages and reduces cleaning costs.
