Motor Grader Inspection & Certification in Ras Tanura
Motor graders shape road bases, finish subgrades, maintain desert tracks and haul roads, and level airfield and industrial platforms on Saudi highway and development projects. Accuracy depends on the circle, drawbar and moldboard, while the long wheelbase, tandem drive and articulation hold the machine steady on loose surfaces. Independent inspection checks these precision and safety systems and gives the project a documented condition report. Site of one of the world's largest oil refineries and export terminals, with continuous maintenance and turnaround activity.
Motor Grader inspection in Ras Tanura: local context
Earthmoving on the Ras Tanura peninsula often supports tank farm containment bunds, pipeline corridors and drainage across low-lying coastal ground, where soft, salty sabkha soils are common. Soft ground and uneven fill put extra strain on undercarriages and brakes, and fine dust clogs filters and radiators. EES inspects excavators, loaders and dump trucks on site, including ROPS structures, before they enter refinery and terminal areas.
Motor Grader inspection scope in Ras Tanura
- ✓Circle and drawbar: circle gear teeth, circle drive gearbox, wear strips and shoes, drawbar ball and socket, and the circle slip clutch
- ✓Moldboard: cutting edges and end bits, slide rails and wear inserts, side-shift and tilt cylinders
- ✓Scarifier or ripper, if fitted: shanks, tips, pins and mounting
- ✓Articulation and frame: hinge pin and bearings, steering cylinders, frame cracks and articulation lock
- ✓Tandem drive: chain case oil, tandem pivot wear, wheel bearings and tyres
- ✓Service and parking brake performance, including a parking brake hold test on a slope
- ✓Front wheel lean cylinders, steering response, and secondary steering test
- ✓Cab protection and blade visibility: ROPS and FOPS, mirrors, camera, alarms and lights
Defects commonly found
- ✓Worn circle teeth and loose circle shoes causing blade chatter
- ✓Leaking blade lift or tilt cylinders that drift under load
- ✓Worn tandem chain case or wheel bearings
- ✓Weak parking brake or worn service brake components
- ✓Cracks at the articulation frame hinge or drawbar mountings
Standards
- ✓ISO 3471 (roll-over protective structures)
- ✓ISO 3450 (braking systems of rubber-tyred machines)
- ✓ISO 5010 (steering requirements for rubber-tyred machines)
- ✓ISO 20474 series (earth-moving machinery safety)
Testing
Not applicable: motor graders are not lifting appliances. Brake and parking brake tests, steering and secondary steering checks, and blade lift, tilt and circle drive function tests apply instead.
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 motor grader on site in Ras Tanura?＋
Yes. Our inspectors travel to your yard or project site in Ras Tanura, including Ras Tanura Refinery and Ras Tanura Terminal, so the equipment does not need to be moved.
Which industries in Ras Tanura request motor grader inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical.
What is the most important item to check on a motor grader?＋
The circle and drawbar system and the brakes and steering are key, because they determine blade accuracy and machine control. Cracks around the articulation frame are also a priority.
Can a grader be inspected on a remote road project site?＋
Yes, inspections can usually be carried out where the machine is working, provided there is safe access and a stretch of level ground for brake and steering checks. Confirm the site arrangements with your inspection provider in advance.
