Crawler Crane Inspection & Certification in Yanbu
Crawler cranes carry a lattice boom on tracked undercarriages and are chosen for heavy lifts that require low ground pressure and the ability to move with a load, such as pipe-rack steel, reactors and bridge girders on Saudi industrial and infrastructure projects. Their capacity depends on boom and jib configuration, counterweight, track extension and the bearing capacity of the ground beneath. Independent inspection should confirm that the assembled boom, pendants, rope system and ground preparation all support the configuration shown on the load chart. Yanbu Industrial City is a major petrochemical and refining centre on the Red Sea.
Crawler Crane inspection in Yanbu: local context
Refinery and petrochemical construction and maintenance work at Yanbu typically relies on mobile and crawler cranes setting vessels, columns and pipe-rack modules next to operating units, so crane documentation and condition are checked before the first lift. Coastal wind and soft ground under outriggers make load chart and LMI checks especially important. EES inspects and load tests cranes on site at Yanbu Industrial City, aligned with ASME B30.5, before lifts begin.
Crawler Crane inspection scope in Yanbu
- ✓Lattice boom and jib: main chords, lacing members, dents, straightness, weld cracks and pin hole wear
- ✓Boom pendant ropes and boom hoist rope, including end terminations, equalisers and wear at sheaves
- ✓Mast, gantry and boom stops, backstops and boom angle indicator
- ✓Track shoes, rollers, idlers, sprockets and track tension, plus carbody and track frame welds
- ✓Counterweight and carbody weight installation, identification and the pins and retainers securing them
- ✓Drum hoists, lagging, clutches, brakes and rope spooling, including the ratchet and pawl locks
- ✓Rated capacity limiter or LMI setup for the specific boom length, jib and counterweight configuration
- ✓Slew bearing and swing gear, travel motors and gearboxes, and hydraulic hoses and fittings
Defects commonly found
- ✓Bent or dented boom chord and lacing members from previous transport or assembly damage
- ✓Elongated pin holes or worn boom connection pins at section joints
- ✓Worn track shoes, rollers or loose track tension causing track derailment risk
- ✓Hoist drum brake or clutch wear giving poor holding power under full load
- ✓Rated capacity limiter set to the wrong configuration or its sensors damaged
Standards
- ✓ASME B30.5 Mobile and Locomotive Cranes
- ✓ISO 4309 Cranes - Wire ropes - Care and maintenance, inspection and discard
- ✓OSHA 29 CFR 1926 Subpart CC (Cranes and Derricks in Construction)
- ✓Manufacturer specifications and load charts
Testing
A rated-capacity load test is typically carried out at 100%-125% of rated capacity at selected radii for the assembled boom configuration, depending on the standard and client, on ground prepared or matted for the track bearing pressure.
Frequency
Typically at least annually, with an inspection after each assembly or reconfiguration for a project and before critical or heavy lifts.

FAQs
Can you inspect a crawler crane on site in Yanbu?＋
Yes. Our inspectors travel to your yard or project site in Yanbu, including Yanbu Industrial City and Yanbu Commercial Port, so the equipment does not need to be moved.
Which industries in Yanbu request crawler crane inspection?＋
Typically operators and contractors in the Madinah Province from these sectors: Vision 2030 Mega-Projects; Oil, Gas & Petrochemical; Ports, Logistics & Warehousing; Power & Utilities.
What ground preparation is needed before a crawler crane load test?＋
The crane needs firm, level ground or crane mats designed for its bearing pressure at the test configuration. Loose sand or uncompacted fill commonly needs compaction or matting to prevent settlement while the load is lifted.
How are the lattice boom sections of a crawler crane inspected?＋
Inspectors check main chords and lacing for dents, bends and cracks, examine pin holes for ovality, and confirm the assembled boom is straight within the manufacturer's tolerances before any load test.
