Tower Crane Inspection & Certification in Ras Tanura
Tower cranes dominate high-rise, commercial and giga-project construction in Riyadh, Jeddah and the Eastern Province, working at height for months with little supervision of the structure itself. Wind, dust and thermal cycling load the mast, jib and bolted connections, and operators cannot see most of the critical joints from the cab. Inspection after erection, after each climb and at regular intervals gives the site a documented basis for safe use. Site of one of the world's largest oil refineries and export terminals, with continuous maintenance and turnaround activity.
Tower Crane inspection in Ras Tanura: local context
Heavy lifts at Ras Tanura Refinery often include exchanger bundles, column sections and large motors inside congested process units, where working radius and ground bearing are tightly limited. Sea breezes add wind loading to boom work. EES inspects and load tests mobile and crawler cranes, verifies LMI and limit switches, and reviews load charts before mobilisation.

Testing
A rated-capacity load test is typically carried out after erection at 100%-125% of rated capacity, depending on the standard and client, at the maximum radius (tip load) and at the radius of maximum rated load, with limit switches and the load limiter verified during the test.
Frequency
Typically after erection and before first use, after each climb or major modification, and then at regular intervals set by the manufacturer, project rules and client requirements.
