What is a crane 250-hour service procedure?
A 250-hour service is the first tier of scheduled preventive maintenance for a mobile crane (all-terrain or truck-mounted). It is performed every 250 engine hours (or approximately every 4-6 weeks of full-time operation) and is classified as a minor service. The procedure covers engine oil and filter replacement, air filter inspection, fuel system maintenance, hydraulic system checks, wire rope visual inspection, hook and rigging checks, boom section inspection and lubrication, slew bearing greasing, outrigger servicing, LMI/RCI operation verification, safety device testing (anti-two-block, hoist limits), electrical checks and fire extinguisher verification. Unlike a daily pre-start check (which confirms the crane is safe to operate), the 250-hour service involves actual maintenance actions: draining and replacing fluids, replacing filters, greasing components and testing safety systems. It is typically performed by a qualified mechanic or crane technician, not the operator.
Mobile cranes are classified as high-risk plant under the WHS Regulations 2011, Chapter 5, and must be registered with the relevant state or territory regulator. AS 2550 requires that cranes be maintained in accordance with the manufacturer's recommendations and that all maintenance activities be documented. The 250-hour service is the primary interval for detecting early-stage wire rope degradation, hydraulic system contamination and boom structural issues before they escalate into safety-critical failures. On construction and infrastructure projects, crane downtime has a cascading impact on programme schedules, subcontractor coordination and site productivity. Operators who maintain a disciplined 250-hour service regime benefit from fewer unplanned breakdowns, lower total cost of ownership and stronger compliance records when presenting equipment for annual inspections or responding to regulator inquiries after an incident.

Benefits of using this crane 250-hour service procedure
- Reduced breakdowns: regular oil, filter and fluid changes prevent engine and hydraulic failures that cause unplanned downtime and costly project delays.
- Wire rope safety: visual inspection at every 250-hour service catches broken wires, corrosion and kinks before they become a dropped-load hazard.
- LMI/RCI reliability: regular testing of load moment indicators ensures overload protection systems are functioning correctly.
- Lower repair costs: a 250-hour service costs a fraction of an emergency breakdown repair. Catching issues early prevents cascading damage to boom, slew and hydraulic systems.
- Compliance: documented service records demonstrate that the crane is maintained to AS 2550 and WHS standards, supporting insurance and regulatory obligations.
- Resale value: a complete service history with documented 250, 500 and 1,000-hour services increases the crane's value at trade-in or disposal.

What to include in a crane 250-hour service procedure
This crane 250-hour service procedure covers 8 key areas:
- Engine: drain and replace engine oil (15W-40), replace oil filter, inspect air filter, drain fuel/water separator, check coolant, inspect fan belts.
- Hydraulic system: check hydraulic oil level.
- Wire ropes and rigging: visual wire rope inspection (broken wires, corrosion, kinks, bird-caging), check hook throat opening, safety latch and swivel, inspect sheaves and pulleys.
- Boom and structure: inspect boom sections for cracks, dents and corrosion, grease boom pivot pins, grease boom extension slides and pads.
- Slew system: grease slew bearing.
- Outriggers: grease outrigger pins and cylinders, check outrigger pad condition.
- Safety systems: inspect LMI/RCI operation, test anti-two-block device, test hoist limit switches.
- Electrical and safety devices: check battery, test lights, horn and alarm, check fire extinguisher.
How to use this crane 250-hour service procedure
- Position the crane on firm, level ground with the boom fully retracted and lowered, outriggers retracted, engine shut down and keys removed. Allow the engine to cool before draining oil.: Park on a firm, level surface away from overhead power lines and traffic. Retract the boom fully and lower it to the boom rest. Retract all outriggers. Remove the ignition key and allow the engine to cool for at least 15 minutes before draining oil.
- Record the equipment details and current hour meter reading at the top of the service procedure form.: Capture the crane registration, fleet number, make, model, maximum capacity, boom length and the current engine hour meter reading. Compare the reading against the previous service to confirm the correct 250-hour interval has elapsed.
- Start with the engine section: drain the old engine oil, replace the oil filter, fill with new oil to the correct level, then inspect the air filter, drain the fuel/water separator and check coolant.: Use the manufacturer-specified oil grade (typically 15W-40). Refill to the full mark on the dipstick. Check the air filter restriction indicator and replace the element if in the red zone. Drain the fuel/water separator bowl completely and check coolant level and concentration.
- Check hydraulic oil level. Inspect wire ropes visually for broken wires, corrosion, kinks and bird-caging. Check hook throat opening, safety latch and swivel. Inspect sheaves and pulleys.: Check hydraulic oil on the sight glass with the boom retracted and lowered. Inspect the full length of each wire rope for broken wires (count visible breaks per lay length), corrosion, kinking and bird-caging. Measure hook throat opening with a calliper and compare to the rejection limit. Verify the safety latch springs closed and the swivel rotates freely.
- Inspect boom sections for cracks, dents and corrosion. Grease boom pivot pins, boom extension slides and pads. Grease slew bearing.: Inspect each boom section at welds, pivot points and high-stress areas. Look for paint cracking that may indicate underlying stress. Apply EP2 grease to all boom pivot pins, extension slide pads and the slew bearing grease nipple until fresh grease purges from the seal.
- Grease outrigger pins and cylinders. Check outrigger pad condition.: Apply EP2 grease to each outrigger pivot pin and cylinder mount pin. Inspect outrigger pads for cracking, deformation or excessive wear. Check outrigger cylinder chrome rods for scoring or pitting that could cause seal failure.
- Test safety systems: inspect LMI/RCI operation, test anti-two-block device and hoist limit switches.: Power up the LMI/RCI and verify it displays correct boom length and angle. Slowly raise the hook to trigger the anti-two-block device and confirm it stops the hoist. Test both upper and lower hoist limit switches by approaching each limit and confirming the system stops. Reset all devices after testing.
- Check the battery, test all lights, horn and alarm. Check fire extinguisher pressure, pin, seal and expiry.: Inspect battery terminals for corrosion and ensure connections are tight. Test all exterior lights including work lights, indicators and beacon. Sound the horn and reversing alarm. Confirm the fire extinguisher gauge is in the green zone, the pin and seal are intact, and the service date has not expired.
- Start the engine and check for leaks, abnormal noises or warning lights. Check the oil pressure gauge and all instrument readings. Record any defects or recommendations in the notes section.: Run the engine and monitor oil pressure, coolant temperature and charge indicators. Walk around the crane checking for oil, coolant or hydraulic leaks. Operate the slew, hoist and boom extend/retract functions briefly to check for smooth operation. Record all defects with severity and recommended actions.
- Set the next service due hours (next 250-hour and next 500-hour intervals). Sign off and update the crane's maintenance log.: Calculate the next 250-hour and 500-hour service due hours from the current reading. Update the service sticker in the cab, the crane maintenance log book and the fleet management system. Obtain sign-off from the service technician.

Mobile cranes should receive a 250-hour minor service every 250 engine hours, which equates to roughly every four to six weeks of full-time operation. Between scheduled services, the crane operator must complete a daily pre-start inspection covering wire ropes, hook, safety devices, lights, fluid levels and general condition before each shift.
The 500-hour intermediate service is due at every second 250-hour interval and adds wire rope measurement, brake inspection and LMI calibration. The 1,000-hour major service adds hydraulic oil change, structural NDT and load testing. Cranes that sit idle for extended periods should still receive a service at least every six months to address time-based degradation. Always follow the crane manufacturer service schedule and any site-specific requirements.
