Belt conveyor with automatic belt control
One property of belt conveyors (1) is that they
give way under load on inclines such as on slop-
ing terrain or if they are loaded on one The au-
tomatic belt control prevents one-sided running
of the conveyor belt on AMAZONE ZG-TS trailed
spreaders.
The conveyor belt is tensioned in the floor belt
with automatic belt control between the drive
drum (2) and the pulley (3).
While the drive drum is secured rigidly in the
floor belt, the pulley can turn around the swivel
axle (4). The belt conveyor is also guided be-
tween two control rollers (5), which are connect-
ed to the pulley by a control frame (6).
If the belt conveyor runs outwards due to a one-
sided load, the control rollers follow this move-
ment. Consequently, this causes the pulley to
turn around the swivel axle. As a result, the dis-
tance between the pulley and the drive drum
increases on the side toward which the belt con-
veyor is moving.
The larger distance causes the belt conveyor to
return to the middle and continue to settle down
in the middle.

Tensioning the belt conveyor:
The conveyor belt is pretensioned in the floor
belt for stable and uniform belt running. If the
conveyor belt should run unevenly under certain
circumstances, the conveyor belt must be re-
tightened on both sides as follows:
1. Loosen the lock nut.
2. Increase the pretension using the setting
nuts.
The adjustment distance of the setting nuts
(3) must be the same on both sides of the floor
belt. Both setting nuts should not be turned by
more than ½ a spanner rotation.
3. Tighten the lock nuts.
4. Check if the conveyor belt is driven evenly
again.
