5.3 CHAIN TENSION
E
D
C
The tension of the chains should be checked after every 100
hours of operation.
If the
deflection exceeds 150 mm
, the chains need to be
tightened up.
Procedure:
Open the shutter (C on photo opposite) according to the procedure described for conveyor cleaning.
- Loosen check nut (D).
- Tighten up nut (E).
- Tighten check nut (D).
- Make sure that both sides of the conveyor are
tightened by identical amounts.
- Close the shutter as described in the section
on conveyor cleaning.
Note: When the chain tension adjuster has reached its limit of travel, the left and right-hand chains
can be shortened by two links.
Never fully tighten the chains. Always leave a deflection of at least 50
mm (Figure 1).
