This conveyor has a Positive Pinch Drive.
When loading on the belt gets heavier, the pinch
roller tightens against the drive roller in proportion.
This provides more torque.
Tighten the tension bolts completely.
When the conveyor belt is tensioned correctly, the
arm at the end of the spring should sit vertical. It can
also be angled back, away from the tension bolt by
as much as 2 inches. This indicates that the belt is a
well adjusted, and is a good length.
The arm should never be angled towards the tension
bolt. This indicates the belt is too long. Measure the
angle. If the belt angles 2 inches away from vertical,
cut and re-lace the belt 4 inches shorter.
If the arm touches the far edge (away from the tension
bolt), the belt is too short. Remove and replace with
longer belt.
4.3.2 Swing-Out Conveyor Belt Tension:
If equipped with a swing-out conveyor, tension its
belt as follows:
WARNING: Rotating Belt Hazard
Turn off engine, lock-out power and wait
for all components to stop moving before
adjusting the belt.
1. Loosen the roller bearing anchor bolts.
2. Use the idler roller adjustment bolts (at the front
of hopper) to set the tension of the belt.
See Figure 83
IMPORTANT:
Adjust in small increments and check often.
