12. Final Checks, Tracking, Start-Up and Maintenance

Belt Tracking
Tracking of the belt is very important for optimum results.
1. To correct any tracking problems.
• First adjust the boot bearing plates.
• Adjust the take-up screws downward on the side that the belt is tracking toward.
2. If this does not correct the problem or if the belt is tracking properly on the boot pulley but not the
head pulley, further adjustments to the head pulley may be required.
3. The bearing side that the belt is tracking toward may need to be shimmed to compensate.
• Loosen the head bearing bolts that go through the head angle.
• Use the jacking screws to raise the bearing.
• Place a full shim the bearing base.
• Back off the screws.
• Re-tighten the bearing mounting bolts.
NOTE:
Use thin shims to make small adjustments until the belt tracks properly.
Start-Up
Once you are sure all installations, safety checks, adjustments and lubrications have been completed:
1. Run the elevator for WITHOUT LOAD an initial break-in period of several hours.
2. Look and listen for any irregularities before running any material through the unit.
3. Re-check all moving parts and adjust as needed.
4. Adjust belt for final tension under load as needed.
Maintenance
Regularly scheduled maintenance helps ensure long life and safe operation of the unit.
1. Routine maintenance checks may include general wear, loose nuts and bolts, electrical wiring,
contacts, switches, misalignment, guy wire inspection, bearing seals and lubrication and oil content
for gearbox.
2. The belt will stretch after installation and may need further adjustment. Expect some stretching during
the first few weeks of operation.
3. On manual take-up boots, belt tension should be maintained by turning the boot take-up screws
slowly and evenly to maintain proper tracking. When the screw adjustment is completely used, the
belt will have to be re-spliced.
NOTE:
Good belt tension is critical for proper traction on the pulley and optimum performance.
