Chain tension, conveyor (1)
Check chain tension:
When the conveyor chain is correctly
tensioned, the lower edge of the chain
is approx. 20-25mm over the lower edge
of the chassis.
m
The conveyor chains should not be too
tight or too slack. An excessively taut
chain can cause the chain to be stopped
or to break when material falls into the
space between the chain and the
sprocket.
An excessively slack chain may catch on
protruding objects and be destroyed.
Adjustment of chain tension:
A
The chain tension is adjusted with
grease tensioners. The filling connec-
tions (A) are located behind the bumper
on the left and right sides.
- Add grease with a grease gun until the
correct chain tension is set.
