What is a conveyor belt 250-hour service procedure?
A 250-hour service is the first tier of scheduled preventive maintenance for a conveyor belt system. It is performed every 250 operating hours and is classified as a minor service. The procedure covers belt tension and tracking adjustment, belt surface inspection, splice and joint checks, roller and pulley inspection (carry, return, impact, drive and tail), scraper and cleaner checks, chute liner and skirting rubber inspection, motor and gearbox checks, bearing greasing, guard checks and emergency stop testing. Unlike a daily pre-start check (which confirms the conveyor is safe to operate), the 250-hour service involves hands-on maintenance: adjusting tension, greasing bearings, inspecting wear components and testing safety devices. It is typically performed by a qualified fitter or maintenance technician.
Conveyor belt incidents remain a significant source of serious workplace injuries in Australia, particularly entanglement at nip points and crush injuries during maintenance. Under the WHS Act 2011, the PCBU must ensure that plant is maintained so it remains safe and without risks to health. AS 4024.3611:2015 (Safety of Machinery, Conveyors, Belt Conveyors for Bulk Materials Handling) sets out guarding, emergency stop and pull-cord requirements specific to belt conveyors, while AS 1755:2000 (Conveyors, Safety Requirements) provides general safety requirements including lockout/tagout procedures for maintenance activities. The 250-hour service includes testing all emergency stops and pull-cords along the conveyor length, verifying that interlocked guards function correctly and confirming that isolation procedures are followed before hands-on maintenance begins. Consistent documentation of 250-hour service data also feeds directly into planning for the 1,000-hour major service, ensuring that wear trends on belts, rollers and scrapers are tracked over time and replacement decisions are based on measured condition rather than reactive failure.

Benefits of using this conveyor belt 250-hour service procedure
- Reduced unplanned downtime: regular belt, roller and scraper checks prevent failures that stop production and cause costly delays.
- Extended belt life: correct tension, tracking and scraper adjustment reduce belt wear, edge damage and splice failure.
- Lower repair costs: catching a seized roller or worn scraper early prevents belt damage that costs thousands to repair or replace.
- Operator safety: testing emergency stops, pull-cords and checking guards at regular intervals reduces the risk of conveyor-related incidents.
- Compliance: documented service records demonstrate that equipment is maintained to WHS standards, supporting insurance and regulatory obligations.
- Throughput consistency: a well-maintained conveyor runs at consistent speed and capacity, supporting production targets.

What to include in a conveyor belt 250-hour service procedure
This conveyor belt 250-hour service procedure covers 6 key areas:
- Belt: check tension and adjust, check tracking and alignment, inspect surface for damage, check splices and joints, inspect belt speed.
- Rollers and pulleys: inspect carry rollers (idlers), return rollers, impact rollers, drive pulley lagging, tail pulley and take-up mechanism.
- Scrapers and seals: check belt scrapers and cleaners (primary and secondary), inspect chute and hopper liners, check skirting rubber and seals.
- Drive system: inspect motor (temperature, vibration, noise), check gearbox oil level and condition.
- Lubrication: grease all bearings (drive, tail, idler, return).
- Safety: check all guards and covers, test emergency stops and pull-cords/rip-cords.
How to use this conveyor belt 250-hour service procedure
- Isolate and lock out the conveyor. Confirm the belt has stopped and all stored energy is released. Follow your site's isolation procedure.: Apply lockout/tagout to the motor isolator. Verify zero energy by pressing the start button and confirming no movement. For gravity take-up conveyors, ensure the counterweight is secured. Wait for the belt to stop completely before approaching nip points.
- Record the equipment details and current hour meter reading at the top of the service procedure form.: Record the conveyor designation, belt width, length, speed, motor size and the current operating hour meter reading. Compare the reading against the previous service to confirm the correct 250-hour interval has elapsed.
- Start with the belt: check tension and adjust if required, check tracking and alignment, inspect the belt surface for cuts, tears and edge damage, check splices and joints.: Check belt sag between idlers (typically 2-3% of idler spacing is ideal). Adjust the screw or gravity take-up to achieve correct tension. Inspect the belt surface for cuts longer than 50 mm, edge fraying or gouges that expose the carcass. Check vulcanised or mechanical splice edges for lifting or separation.
- Inspect all rollers: carry rollers (idlers) for spin, seizure and alignment, return rollers, impact rollers at the loading point, drive pulley lagging and tail pulley with take-up mechanism.: Spin each roller by hand. A seized or stiff roller will cause belt wear and tracking issues. Mark seized rollers for replacement. Check that impact rollers at the loading zone are not cracked or flattened. Inspect drive pulley lagging for wear or delamination and check the tail pulley for material build-up.
- Check belt scrapers and cleaners (primary and secondary). Inspect chute and hopper liners for wear. Check skirting rubber and seals.: Verify the primary scraper contacts the belt evenly across its full width. Check the secondary scraper blade for wear and replace if worn past the indicator line. Inspect chute liner plates for holes or grooving that allow material spillage. Confirm skirting rubber seals tightly against the belt edge.
- Check the motor (temperature, vibration, noise) and gearbox oil level and condition.: Feel the motor housing for excessive heat (above 70 degrees Celsius above ambient is a concern). Listen for bearing noise. Check gearbox oil level on the sight glass or dipstick. If the oil appears milky (water contamination) or contains metal particles, note it for early oil change at the next service.
- Grease all bearings: drive, tail, idler and return roller bearings. Use EP2 lithium complex grease.: Apply the manufacturer-specified quantity of EP2 grease to each bearing nipple. For pillow block bearings on drive and tail pulleys, typically three to five pumps from a standard grease gun. Do not over-grease sealed idler bearings. Wipe excess grease from around seals.
- Check all guards and covers are fitted. Test emergency stops and pull-cords/rip-cords.: Verify guards are in place at the head pulley, tail pulley, return rollers and all nip points. Test each emergency stop button along the conveyor length and confirm the conveyor stops. Pull the rip-cord or pull-cord from both sides and confirm shutdown occurs. Reset all devices after testing.
- Remove isolation and run the conveyor. Check belt tracking under load, listen for abnormal noises and observe belt speed. Record any defects in the notes section.: Start the conveyor empty and observe belt tracking for two full belt revolutions. Then run under load and confirm the belt does not wander to one side. Listen for roller squealing, belt slapping or gearbox noise. Verify belt speed matches the design specification.
- Set the next service due hours (next 250-hour and next 1,000-hour intervals). Sign off and update the conveyor's maintenance log.: Calculate the next 250-hour and 1,000-hour service due hours from the current reading. Update the service tag on the conveyor, the maintenance log and the asset management system. Obtain sign-off from the service technician and the area supervisor.

Back to download formHow often should you complete this service procedure?
The 250-hour minor service should be performed every 250 operating hours. For conveyors running on a single shift (8-10 hours per day), this equates to roughly every five to six weeks. Conveyors running 24/7 will reach the interval in approximately 10-11 days. Between scheduled services, operators should perform daily pre-start checks covering belt tracking, visible damage, emergency stop function and unusual noise.
Conveyors handling abrasive materials such as crusite, ore or aggregate may benefit from a shortened 150-200 hour interval for scraper and roller inspection. The 250-hour service data feeds into planning for the 1,000-hour major service, so consistent data collection at each interval is important. Always refer to the conveyor and component manufacturer service manuals for your specific system.
