Hiab (Crane-Mounted) Truck Inspection & Certification in Dhahran
Hiab trucks, also called lorry loaders, carry a hydraulic knuckle-boom crane on a truck chassis and are widely used in Saudi Arabia for delivering and positioning pipes, steel, containers and equipment. The crane and the truck work as one machine: stability depends on the subframe, the stabilisers and the axle loads as much as on the crane itself. Third-party inspection and load testing confirm the crane can lift its rated loads and that the truck underneath is fit to carry the crane and the cargo.

Hiab (Crane-Mounted) Truck inspection in Dhahran: local context
Dhahran is part of the Dammam-Al Khobar-Dhahran urban cluster, so prime movers, lowbeds, tankers and flatbeds regularly move between ports, yards and gated premises such as Aramco Dhahran. EES inspects brakes, tyres, couplings, tie-down points and tanker fittings, so vehicles pass gate checks with current inspection certificates in hand.
Hiab (Crane-Mounted) Truck inspection scope in Dhahran
- ✓Crane subframe, mounting brackets, bolts and chassis rails for cracking, shifted components and evidence of overload or poor repair
- ✓Stabiliser beams, cylinders and pads, and the interlock or sensor that prevents crane operation until the stabilisers are deployed
- ✓Boom sections, knuckle joint pins and bushes, and the slew bearing and its bolts for wear, cracks and slack
- ✓Hydraulic cylinders, pilot-operated holding or lowering valves and hoses for drift, leaks and abrasion
- ✓Load moment limiting or overload protection system, checked against the rated capacity chart and the crane plate
- ✓PTO engagement, hydraulic pump, oil tank, filters and oil temperature, plus the cab-side controls and engagement interlock
- ✓Stowed position of the boom, boom rest and transport locks, cab guard or headboard, and the load bed and lashing points for carried cargo
- ✓Truck brakes, steering, tyres and axle load against the combined crane and cargo weight, plus hook, safety latch, any winch rope (examined with reference to ISO 4309), remote control and emergency stop
Defects commonly found
- ✓Cracked or loose crane subframe brackets and mounting bolts after repeated long-radius lifting
- ✓Stabiliser interlock bypassed, or beam position sensors that no longer register
- ✓Worn boom pins and bushes giving excess slack at the knuckle joint
- ✓Leaking holding valves allowing the boom to drift down under load
- ✓Load limiting device out of calibration, or an axle load that exceeds the chassis plate once crane and cargo are on board
Standards
- ✓EN 12999 (loader cranes)
- ✓ASME B30.22 (articulating boom cranes)
- ✓ISO 4309 (wire rope examination and discard)
- ✓Manufacturer specifications and load charts
Testing
A proof load test applies, typically 100%-125% of rated capacity at defined radii depending on the standard and client, with function checks of the boom, stabilisers, holding valves and load limiting device. Load test weights and radii follow the load chart.
Frequency
Typically at least annually, with pre-mobilisation checks and more frequent re-inspection where client or site rules require. A load test is typically repeated after major repair or modification.

FAQs
Can you inspect a Hiab (crane-mounted) truck 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 Hiab (crane-mounted) truck inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Construction & Infrastructure.
Does a Hiab truck need a load test certificate?＋
Most Saudi contractors and operators require a current inspection and load test certificate for loader cranes before they allow lifts on site. The exact test factor depends on the standard and client rules.
Is a Hiab truck inspected as a crane or as a truck?＋
Both. The crane side covers the boom, holding valves and load limiter and is load tested, while the vehicle side covers the chassis, subframe, brakes and axle loading, because the stability of the combined unit depends on each.
