Crawler Crane Inspection & Certification in Saudi Arabia
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.
What we inspect on a crawler crane
- ✓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
Common defects we find
- ✓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
Risks of operating uncertified
- ✓Boom buckling or backward overturn from damaged lattice members or incorrect boom configuration
- ✓Crane settlement or overturn on ground that cannot support the track bearing pressure
- ✓Dropped load from hoist brake or clutch failure, or from a pendant or hoist rope parting
Testing, standards & frequency
Load / performance test
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.
Inspection interval
Typically at least annually, with an inspection after each assembly or reconfiguration for a project and before critical or heavy lifts.
Standards referenced
- ASME B30.5 Mobile and Locomotive Cranes
- ISO 4309 Cranes - Wire ropes - Care and maintenance, inspection and discard

FAQs
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.
