What is a crane 500-hour service?
A 500-hour service is the second tier of scheduled preventive maintenance for a mobile crane (all-terrain or truck-mounted). It is performed every 500 engine hours and is classified as an intermediate service. The procedure carries forward all 250-hour tasks and adds filter replacements (fuel, air, hydraulic return), wire rope measurement (diameter at three points, broken wire count per lay length), sheave groove wear measurement, brake inspection (hoist, slew, travel), winch drum inspection, LMI/RCI calibration verification, slew ring bolt torquing, carrier inspection, outrigger seal checks, hydraulic oil sampling for laboratory analysis, counterweight mounting inspection and safety decal verification. It is performed by a qualified crane technician or heavy plant mechanic.
Benefits of scheduled crane servicing
- Wire rope trend monitoring: measuring diameter and broken wires at the 500-hour interval builds a wear profile that predicts rope replacement before failure.
- Brake confidence: inspecting hoist, slew and travel brakes ensures holding and dynamic braking capacity meet manufacturer specifications.
- LMI/RCI accuracy: checking calibration against the load chart at 500-hour intervals catches sensor drift before it leads to overload events.
- Hydraulic system health: oil sampling detects contamination, wear metals and moisture before they damage pumps and valves. Sampling is far cheaper than component replacement.
- Compliance: documented 500-hour service records support AS 2550 requirements and demonstrate due diligence to regulators and insurers.
- Reduced downtime: catching worn sheaves, loose slew ring bolts or degraded brake linings at the 500-hour interval prevents unplanned failures during lifting operations.

Fluid specifications
General fluid specifications for mobile cranes (all-terrain and truck-mounted). Capacities vary by crane class and manufacturer.
| System | Type / Grade | Approx. Capacity |
|---|---|---|
| Engine oil | 15W-40 CI-4 / CK-4 | 15 - 30 L |
| Hydraulic oil | ISO VG 46 (AW 46) | 150 - 300 L (system) |
| Coolant | 50/50 ethylene glycol | 25 - 40 L |
| Slew ring gear grease | EP0 or EP1 | As required |
| Wire rope lubricant | Wire rope dressing | As required |
| Grease | EP2 lithium complex | As required |
Specifications are general guidelines. Always refer to the manufacturer's service manual for your specific make and model.
Parts and consumables
Have the following parts and consumables ready before starting the 500-hour service (includes 250-hour items):
- Engine oil (15W-40 CI-4/CK-4) - 15-30 litres
- Engine oil filter - 1
- Fuel filter element - 1
- Air filter element - 1
- Hydraulic return filter - 1
- Fuel/water separator element - 1
- EP2 grease cartridges - 4-6
- Wire rope lubricant - as required
- Oil sample bottle (hydraulic) - 1
- Wire rope measurement log - 1
- Coolant (pre-mixed or concentrate) - as required
- Rags, drip tray and waste oil container
Look up part numbers in the manufacturer's parts manual for your specific make and model before ordering.
How to perform a crane 500-hour service
- Complete the full 250-hour service procedure first. All 250-hour tasks carry forward to the 500-hour interval.
- Replace the fuel filter, air filter and hydraulic return filter.
- Measure wire rope diameter at three points along the rope using a vernier calliper. Count and record broken wires per lay length. Compare against rejection criteria (AS 2759 and manufacturer limits). Inspect sheave grooves for wear and measure groove dimensions.
- Inspect hoist, slew and travel brakes. Measure brake lining thickness and check adjustment. Inspect the winch drum for rope winding pattern and flange condition.
- Check LMI/RCI calibration by comparing displayed values against the crane's load chart at a known radius and load.
- Torque slew ring mounting bolts to the manufacturer's specification. Inspect the carrier: tyres, brakes, steering and suspension. Check outrigger cylinder seals for leaks.
- Take a hydraulic oil sample from the designated sampling port. Label the bottle with the crane ID, hours and date. Send to the laboratory for analysis.
- Inspect counterweight mounting bolts and brackets. Verify all safety decals are legible and in the correct positions.
- Record all measurements, defects and recommendations in the notes section. Set the next service due hours (next 500-hour and next 1,000-hour intervals). Sign off and update the crane's maintenance log.
In MapTrack, you can schedule services based on hour meter readings, get automatic reminders, complete service procedures on mobile and link every record to the crane. Book a demo to see how.

Back to download formCrane service interval hierarchy
Crane maintenance follows a tiered schedule where each level includes all tasks from the level below. This is called carry-forward or cumulative servicing.
Engine oil and filter, grease points, wire rope visual check, safety system tests. Estimated 2-3 hours.
500 hours - Intermediate service (you are here)
All 250-hour tasks plus filter replacements, wire rope measurement, brake inspection, LMI calibration, slew ring bolt torquing and hydraulic oil sampling. Estimated 4-6 hours.
1,000 hours - Major service
All 500-hour tasks plus hydraulic oil change, full brake overhaul, structural NDT and load testing. Estimated 8-12 hours.
2,000 hours - Overhaul service
All 1,000-hour tasks plus slew ring assessment, boom structural inspection, hydraulic pump and motor inspection. Typically 2-3 days.
In MapTrack, you can configure service schedules by engine hours and receive automatic alerts when each interval is due.
Frequently asked questions
- What is included in a crane 500-hour service?
- A 500-hour crane service is an intermediate service that carries forward all 250-hour tasks (engine oil and filter, grease points, wire rope visual check, safety system tests) and adds fuel filter replacement, air filter replacement, hydraulic return filter replacement, wire rope diameter measurement at 3 points, broken wire counting per lay length, sheave groove wear measurement, hoist/slew/travel brake inspection (lining thickness and adjustment), winch drum inspection, LMI/RCI calibration check against load chart, slew ring mounting bolt torquing, carrier inspection (tyres, brakes, steering, suspension), outrigger cylinder seal check, hydraulic oil sampling, counterweight mounting inspection and safety decal verification. It takes approximately 4 to 6 hours.
- What additional items does a 500-hour crane service include compared to a 250-hour service?
- Beyond the 250-hour service, the 500-hour interval adds: replacing the fuel filter, air filter and hydraulic return filter, measuring wire rope diameter at 3 points and recording broken wires per lay length, measuring sheave groove wear, inspecting hoist/slew/travel brakes for lining thickness and adjustment, inspecting the winch drum, checking LMI/RCI calibration against the load chart, torquing slew ring mounting bolts, inspecting the carrier (tyres, brakes, steering, suspension), checking outrigger cylinder seals, taking a hydraulic oil sample for laboratory analysis, inspecting counterweight mounting and verifying all safety decals are legible.
- Why is wire rope measurement important at 500 hours?
- Wire rope measurement at the 500-hour interval quantifies rope wear with actual diameter readings at three points along the rope and a broken wire count per lay length. This data is compared against rejection criteria in AS 2759 and the crane manufacturer's limits. Measuring at regular intervals establishes a wear trend that helps predict when replacement will be needed, rather than relying solely on visual inspection. Catching diameter reduction or excessive broken wires early prevents rope failure during lifting operations.
