Chain tension, conveyor (1)
Check chain tension:
When the conveyor chain is tensioned correctly, the lower edges of both chain sags
(before and after the chain guide) hangs approx. 170 mm above the ground.
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 be-
tween the chain and the sprocket.
If the chains are too slack, it may get stuck in the protruding objects and be damaged.
Adjustment of chain tension:
A
One adjusting screw is located on both
halves of the conveyor for adjusting the
chain tension.
A
The adjusting screws are located at the
reversal behind the crossbeam.
A
A special wrench for the lock nut (A) is
included in the scope of supply of
the vehicle.
- Unfasten lock nut (A) at the reversal.
- Adjust the chain tension using the ad-
justing screw (B).
