Tread Roller Installation; Pressure Adjustment - HYTROL ABLR Manual De Instalación Y Mantenimiento

HOW TO STEER THE BELT
Condition 1. . .When the belt is running in the direction (FLOW) with the arrow, but tracking
(drifting) towards Side "X", move the Snub Idler nearest the INFEED end of Side "Y" towards
the DISCHARGE end of the conveyor.
Condition 2. . . When the belt is running in the direction (FLOW) with the arrow, but tracking
(drifting) towards Side "Y", move the Snub Idler nearest the INFEED end of Side "X" towards
the DISCHARGE end of the conveyor.
If Belt Direction (FLOW) is reversed, all the above conditions will remain the same as in
Figure 6C, except you are now viewing the conveyor from the opposite end.
If belt continues to track improperly, re-check all items covered in "Pre-Tracking Inspection"
and make corrections as necessary.

• Tread Roller Installation

In order to thread the belt through the conveyor, some of the tread rollers were
removed. Reinstall all tread rollers that may have been removed.
To drive the end rollers, they are connected with "O"-Rings as shown in Figure
6E. Note that the four end rollers have two grooves.
CAUTION! Only trained personnel should track conveyor belt which must
be done while conveyor is in operation. All guards should be in place while
tracking conveyor belt.
NOTE: In all conditions, you are viewing the Conveyor Belt from the
INFEED end. All corrections will be made from the INFEED end of

• Pressure Adjustment

The Model ABLR is equipped with spring-loaded pressure frames to apply
the driving force between the belt and tread rollers. The conveyor has been
adjusted at the factory; however, if the belt is moving but the tread rollers are
not turning, follow the steps below to adjust each zone.
1. With Zone Driving, make sure pressure frame is set properly (Figure 6F).
2. If not, tighten guide bolt only enough to bring guide stop in contact with bed
spacer (Detail A). Tightening beyond this point will not increase drive.
CAUTION! Do not attempt to adjust conveyor until it has been test run.
See trouble Shooting Guide for definition and solution to problems.
