Mobile Harbour Crane Inspection & Certification in NEOM
A mobile harbour crane is a high-capacity portal-type crane on a mobile base with a slewing superstructure and luffing boom, used to handle bulk, general cargo and containers on quays without fixed rail infrastructure. Saudi ports use them at general cargo berths, bulk terminals and industrial ports, where they switch between hooks, grabs and spreaders through the day. Frequent changes of attachment and heavy cycles make independent checks of the slew ring, ropes and load limiters particularly valuable. The giga-project in north-west Saudi Arabia, mobilising vast fleets of heavy equipment and workers.
Mobile Harbour Crane inspection in NEOM: local context
Oxagon's port and coastal marine works, including the marina at Sindalah, call for equipment such as harbour cranes, ship-to-shore cranes and straddle carriers, with floating cranes and lifeboat davits supporting operations beside open water. Salt spray and repeated duty cycles speed corrosion of wire rope, sheaves and structures, so EES inspects and load-tests marine lifting equipment at the quayside and berth, documenting rated capacity and condition.
Mobile Harbour Crane inspection scope in NEOM
- ✓Slew ring bearing checked for play, bolt tightness, abnormal noise and grease condition, with raceway wear assessed in line with manufacturer instructions
- ✓Boom sections, boom pivot pins and luffing cylinders or ropes inspected for cracks, corrosion and pin wear
- ✓Hoist and luffing wire ropes measured for diameter reduction, broken wires and corrosion, with sheaves and drum grooves checked for wear
- ✓Grab, hook block or container spreader examined for jaw wear, rope reeving, twist lock condition and hydraulic hose leaks
- ✓Outrigger beams, pads and mobile base undercarriage checked for structural damage and hydraulic leaks, along with quay support conditions
- ✓Rated capacity limiter, load moment indicator, anemometer, slew and luff limit switches functionally tested
- ✓Hoist, slew and luff brakes tested for holding ability and wear, with slew gearbox and drives inspected
- ✓Cab, controls, emergency stops, travel and outrigger interlocks and fire protection checked for condition and function
Defects commonly found
- ✓Slew ring bolt loosening or raceway wear leading to excessive play
- ✓Boom pin wear and cracking at boom and base connections
- ✓Worn grab jaws, hydraulic hose leaks and damaged reeving on grab systems
- ✓Rated capacity limiter out of calibration or bypassed for the attachment in use
- ✓Outrigger pad damage and hydraulic leaks that cause settling under load
Standards
- ✓ASME B30.4 (portal and pedestal cranes)
- ✓ISO 9927-1 (cranes, inspections, general)
- ✓ISO 4309 (wire ropes, examination and discard criteria)
- ✓Manufacturer specifications and load charts
Testing
A load test is typically carried out with certified test weights at 100% to 125% of rated capacity depending on the standard and client, usually at selected radii on the load chart. The test checks hoisting, luffing, slewing, braking and the rated capacity limiter, and repeats for the attachments and outrigger setups in use.
Frequency
Typically at least annually for a thorough examination, with pre-mobilisation checks, inspection after attachment or boom modification and more frequent re-inspection where client or terminal rules require.

FAQs
Can you inspect a mobile harbour crane on site in NEOM?＋
Yes. Our inspectors travel to your yard or project site in NEOM, including The Line, Oxagon and Sindalah, so the equipment does not need to be moved.
Which industries in NEOM request mobile harbour crane inspection?＋
Typically operators and contractors in the Tabuk Province from these sectors: Ports, Logistics & Warehousing.
What makes a mobile harbour crane inspection different from a standard mobile crane inspection?＋
Mobile harbour cranes carry grabs and spreaders, operate on quay surfaces and are exposed to marine corrosion, so inspectors add checks on attachment reeving, rated capacity settings for each attachment and quay support conditions. The slew ring and boom pins also get close attention.
Can a mobile harbour crane be load tested on the quay?＋
Yes, load testing is commonly carried out on the quay using certified test weights or water bags, subject to quay bearing capacity and the port authority's permit rules. The tester checks the load chart radii and limiter settings used in service.
