Truck-Mounted Crane Inspection & Certification in Dhahran
Truck-mounted cranes place a telescopic boom crane on a standard truck chassis with a separate driving cab, and are one of the most common lifting machines for yard work, pipe delivery, maintenance and light construction across Saudi Arabia. Their capacity depends on the truck frame, subframe fixing and outrigger stability as well as the boom, and many operate with minimal maintenance in hot, dusty conditions. Independent inspection checks both the crane and the chassis it relies on. Headquarters of Saudi Aramco, with a high concentration of contractors operating under Aramco General Instructions.
Truck-Mounted 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.
Truck-Mounted Crane inspection scope in Dhahran
- ✓Chassis frame and crane subframe mounting bolts, welds and any unauthorised modifications
- ✓Power take-off, hydraulic pump and drive-line, plus hydraulic tank level, filters and oil condition
- ✓Front and rear outriggers or stabilisers, extension beams, cylinders and the outrigger-extended interlock
- ✓Telescopic boom, wear pads and extension synchronisation, boom angle and length sensors
- ✓Load moment indicator or overload device and anti-two-block, including the calibration against test weights
- ✓Hoist rope, drum, hook block, safety latch and hoist brake holding
- ✓Slew bearing, slew gearbox and swing brake and lock
- ✓Truck brakes and air system, tyres, steering, lights and cab-side crane controls
Defects commonly found
- ✓Cracked or loose crane subframe mounts and chassis modifications without engineering approval
- ✓Outrigger cylinder leakage or missing outrigger interlock allowing crane use with outriggers retracted
- ✓Worn hydraulic pump or PTO giving low relief pressure, slow boom response and hot, contaminated oil
- ✓Boom wear pads worn out and hydraulic hose abrasion on the boom or turntable
- ✓Hoist rope worn at the end terminations or at sheaves, and non-functioning hook safety latch
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, depending on the standard and client, with the chassis, outriggers and overload device observed during the lift.
Frequency
Typically at least annually, with a check before mobilisation to a new site and more frequent inspection for units on heavy daily duty.

FAQs
Can you inspect a truck-mounted 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 truck-mounted crane inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Construction & Infrastructure.
What is the difference between a truck-mounted crane and a mobile crane?＋
A truck-mounted crane uses a standard truck chassis and a PTO-driven hydraulic system, while many mobile cranes use a purpose-built carrier. They are generally inspected and tested under the same mobile crane requirements.
Why does a truck-mounted crane inspection include the truck chassis?＋
The crane's rated capacity relies on the chassis frame, subframe fixing, brakes and tyres. Cracked or modified chassis members can invalidate the load chart, so they are part of the inspection.
