Mobile Crane Inspection & Certification in Dhahran
Mobile cranes are the general-purpose lifting machines of Saudi construction sites, plant shutdowns and industrial yards from Jubail and Yanbu to Riyadh, typically a telescopic boom on a road-going carrier with hydraulic outriggers. Dust, heat and rough ground accelerate wear on boom slide pads, hydraulic seals and wire rope. Independent inspection and load testing before mobilisation gives the owner and the site operator documented evidence that the structure, safety devices and capacity indicator are fit to lift to the rated chart.

Mobile Crane inspection in Dhahran: local context
Lifts in Dhahran are often building-led: steel and precast elements placed beside occupied offices, laboratories and live roads, where the lift plan and load chart matter as much as capacity. EES examines mobile and tower cranes, load indicators and limiters, slew rings and outriggers, then load tests against standards such as ASME B30.5, with records ready for client and site-entry reviews.
Mobile Crane inspection scope in Dhahran
- ✓Telescopic boom sections for straightness, cracks at section ends, wear pad condition and smooth extension and retraction
- ✓Outrigger beams, jacks and float pads, including cylinder leak-down and holding (pilot-operated check) valves
- ✓Load moment indicator (LMI) accuracy against known test weights, with radius, boom angle and boom length sensors verified
- ✓Anti-two-block switch, overload cut-out, and boom angle and slew limiting functions
- ✓Slew ring bolt torque marks, slew gearbox backlash, and swing brake and lock operation
- ✓Hoist wire rope for broken wires, diameter reduction, corrosion and drum spooling, plus hook block, sheaves and hook safety latch
- ✓Load chart and rated-capacity decals matching the counterweight and boom configuration actually fitted
- ✓Hydraulic hoses, fittings and lift cylinders for leaks and chafing, plus carrier brakes, steering and tyres
Defects commonly found
- ✓Worn boom slide pads causing excessive deflection or sideways play when extended
- ✓Outrigger cylinder drift from leaking seals or failed holding valves
- ✓LMI out of calibration, or an anti-two-block switch that is faulty or bypassed
- ✓Broken wires, core protrusion or kinking in the hoist rope, and worn sheave grooves
- ✓Cracks or distortion at the boom foot, lift cylinder pins or turntable welds
Standards
- ✓ASME B30.5 Mobile and Locomotive Cranes
- ✓EN 13000 Cranes - Mobile cranes
- ✓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 and boom lengths, depending on the standard and client, with the LMI verified against calibrated test weights.
Frequency
Typically at least annually, with pre-mobilisation checks and more frequent re-inspection where client or site rules require.

FAQs
Can you inspect a mobile crane on site in Dhahran?＋
Yes. Our inspectors travel to your yard or project site in Dhahran, including Aramco Dhahran, KFUPM and Techno Valley, so the equipment does not need to be moved.
Which industries in Dhahran request mobile crane inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Construction & Infrastructure.
How often should a mobile crane be inspected and load tested in Saudi Arabia?＋
Most clients and contractors expect a documented third-party inspection at least annually and before mobilising to a new site, with load testing at commissioning and after major repair or modification. Your project lifting procedure and client rules set the exact frequency.
What documents does a mobile crane need before it can lift on site?＋
Typically a current inspection and load test report, the load charts, maintenance records, the operator's competency evidence and any client-specific pre-mobilisation checklist. Requirements differ between projects, so confirm them with the site lifting supervisor.
