Truck-Mounted Crane Inspection & Certification in Saudi Arabia
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.
What we inspect on a truck-mounted crane
- ✓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
Common defects we find
- ✓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
Risks of operating uncertified
- ✓Overturning when lifting without fully extended outriggers or with a defective overload device
- ✓Chassis or subframe fracture from fatigue under repeated heavy lifts
- ✓Load drop from a worn hoist rope or brake, with crushing risk to ground crews
Testing, standards & frequency
Load / performance test
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.
Inspection interval
Typically at least annually, with a check before mobilisation to a new site and more frequent inspection for units on heavy daily duty.
Standards referenced
- ASME B30.5 Mobile and Locomotive Cranes
- EN 13000 Cranes - Mobile cranes
- OSHA 29 CFR 1926 Subpart CC (Cranes and Derricks in Construction)

FAQs
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.
