What is included in a crane 250-hour service?

A 250-hour crane service is a minor service that includes draining and replacing engine oil (typically 15W-40), replacing the engine oil filter, inspecting the air filter, draining the fuel/water separator, checking coolant level, checking hydraulic oil level, visually inspecting wire ropes for broken wires, corrosion, kinks and bird-caging, checking hook throat opening, safety latch and swivel, inspecting boom sections for cracks, dents and corrosion, greasing boom pivot pins, boom extension slides and pads, slew bearing, and outrigger pins and cylinders, checking outrigger pad condition, inspecting LMI/RCI operation, testing anti-two-block device and hoist limit switches, inspecting sheaves and pulleys, checking fan belts, battery, lights, horn and alarm, and checking the fire extinguisher. It takes approximately 2 to 3 hours.

How often should a mobile crane be serviced?

Mobile cranes follow a tiered service schedule based on engine hours. A 250-hour (minor) service covers oil, filters, grease, wire rope visual checks and basic safety system inspections. A 500-hour (intermediate) service adds filter replacements, wire rope measurement, brake inspection, LMI calibration check, slew ring bolt torquing and hydraulic oil sampling. A 1,000-hour (major) service adds hydraulic oil change, full brake overhaul, structural NDT and load testing. Daily pre-start checks are performed by the operator before each shift. Always refer to the manufacturer service manual for your specific make and model.

What safety systems are checked during a crane 250-hour service?

The 250-hour service includes inspecting the LMI/RCI (load moment indicator/rated capacity indicator) operation, testing the anti-two-block device, testing hoist limit switches, checking hook throat opening and safety latch, inspecting wire ropes for defects, checking the fire extinguisher, and testing lights, horn and alarm. These safety systems are critical for preventing overload events and dropped loads.

What is a crane 250-hour service?

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.

Benefits of scheduled crane servicing

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.

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 250-hour service:

Engine oil (15W-40 CI-4/CK-4) - 15-30 litres
Engine oil filter - 1
Fuel/water separator element - 1
EP2 grease cartridges - 4-6
Wire rope lubricant - as required
Coolant (pre-mixed or concentrate) - as required for top-up
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 250-hour service

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.
Record the equipment details and current hour meter reading at the top of the service procedure form.
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.
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.
Inspect boom sections for cracks, dents and corrosion. Grease boom pivot pins, boom extension slides and pads. Grease slew bearing.
Grease outrigger pins and cylinders. Check outrigger pad condition.
Test safety systems: inspect LMI/RCI operation, test anti-two-block device and hoist limit switches.
Check the battery, test all lights, horn and alarm. Check fire extinguisher pressure, pin, seal and expiry.
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.
Set the next service due hours (next 250-hour and next 500-hour intervals). Sign off and update the crane's maintenance log.

Crane 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.

250 hours - Minor service (you are here)

Engine oil and filter, grease points, wire rope visual check, safety system tests. Estimated 2-3 hours.

500 hours - Intermediate service

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.
