Truck Crane & Hydraulic Crane Inspections
"Truck crane" and "hydraulic crane" cover the truck-mounted slewing cranes that sit between two classes people know by other names: bigger and more crane-like than a Hiab-style loader crane, but built on a truck carrier rather than a dedicated all-terrain chassis. If your machine is a hydraulic slewing crane mounted on a truck — with a telescoping boom, a winch and rope, planted outriggers and a rated-capacity system — this is the page for arranging its independent inspection and certification under the AS 2550 series and the AS 1418 design framework.
Because the terminology overlaps, the first thing we do is confirm what the machine actually is, since that decides the inspection scope: a folding-boom crane loading its own vehicle is inspected as a vehicle loading crane, and a crane on a purpose-built all-terrain or rough-terrain carrier as a mobile crane. For the truck-mounted hydraulic slewing crane itself, the inspection covers the telescoping boom and wear pads, the winch, rope and hook block, the slew ring, the outriggers and their interlocks, the hydraulic circuit, the rated-capacity and safe-load systems, and the sub-frame and mounting that tie the crane to the truck chassis. Defects are rated by severity and the outcome documented, so the crane's compliance record is complete and current.

The Process
Identify the crane class
"Truck crane" means different machines to different operators, so we confirm the make, model and configuration first — truck-mounted slewing crane, loader crane or mobile crane — because the correct inspection scope follows from what the machine actually is.
Inspect the lifting structure
The telescoping boom sections, wear pads, slew ring, winch, rope, hook block and connecting pins are examined for wear, distortion, corrosion and fatigue across the load path — the components that carry every lift.
Check outriggers, mounting & safety systems
The outriggers and their interlocks, the sub-frame and mounting to the truck chassis, the hydraulic circuit and the rated-capacity and safe-load systems are checked, because on a truck crane stability and the crane-to-chassis connection are as critical as the boom.
Test, certify & document
Function and, where warranted, load testing verify the crane performs to its rating, defects are rated by severity, and you receive the logbook entries and certification documentation the crane needs to keep working.
Compliance & Standards
Truck-mounted hydraulic slewing cranes are designed within the AS 1418 series and used, sited, maintained and inspected under the AS 2550 series. Routine and periodic inspections keep the crane safe between deeper checks, and a major inspection falls due at the interval set by the relevant standard and equipment class — commonly 5-year or 10-year depending on equipment type and duty. Because the crane and its truck work as one system, the safe-use regime covers the sub-frame and mounting alongside the boom, winch and outriggers — reaction loads pass through the chassis connection on every lift, and it is a known fatigue point on hard-worked units. We work independently of every crane manufacturer, reference the applicable standards generically, and record only what has genuinely been inspected or tested. Keeping the crane's records current is what keeps it compliant, insurable and defensible if an incident is investigated, and we will always identify the correct class and interval for your specific machine rather than forcing it into a generic template.
Why EWP Australia
- Correct classification first — the scope matches what the crane actually is
- Boom, winch, slew, outriggers and chassis mounting assessed as one system
- Rated-capacity and safe-load systems checked in scope
- Independent of manufacturer sales and service networks
- Severity-rated defect reporting for planning repairs
- Australia-wide mobile field service — we come to the crane
Truck Crane vs Loader Crane vs Mobile Crane at a Glance
The terms get used loosely on site — the machine's actual class decides the inspection scope, so identifying it correctly comes first.
| Class | Configuration | Typical Use | Inspection Emphasis |
|---|---|---|---|
| Truck-mounted slewing (truck / hydraulic) crane | Telescoping boom, winch and outriggers on a truck chassis | Taxi-crane lifts, steel, precast and building supply | Boom, winch and rope, slew ring, sub-frame and chassis mounting |
| Vehicle loading (Hiab-style) crane | Folding boom fitted to load its own truck | Self-loading deliveries and transport work | Folding boom knuckles, stabilisers and mounting |
| Mobile crane | Purpose-built all-terrain or rough-terrain carrier | Dedicated craneage and heavier lifts | Carrier, counterweight and full crane systems scope |
| Franna / pick-and-carry crane | Articulated carrier that lifts and travels with the load | Yard work and mobile lifts without outriggers | Articulation joint and dynamic-load structure |
Figures are indicative of typical equipment classes, not a specific unit. Confirm exact specifications for any machine before hire or purchase.
Common Questions
Is a truck crane the same as a Hiab or a mobile crane?
It sits between them, and the terms get used loosely on site. A Hiab-style vehicle loading crane is a folding-boom crane fitted to load its own truck; a mobile crane runs on a purpose-built all-terrain or rough-terrain carrier; a truck crane is a hydraulic slewing crane — telescoping boom, winch and outriggers — mounted on a truck chassis. Each class has its own inspection emphasis, which is why we confirm what your machine actually is before scoping the work. If yours is a loader crane or a mobile crane, our dedicated pages for those classes cover them directly.
What does 'hydraulic crane' mean in practice?
Almost all modern truck-mounted and mobile cranes are hydraulic — the term usually just distinguishes them from older mechanical or lattice-boom machines. When operators search for a hydraulic crane inspection they generally mean a telescoping-boom slewing crane, and the inspection covers the hydraulic circuit itself — pumps, hoses, cylinders and holding valves — alongside the structure, because a holding-valve or cylinder fault can lower a load as surely as a structural failure.
Why does the crane-to-truck mounting matter?
Because every lift's reaction loads pass through it. The sub-frame and mounting bolts that tie the crane to the truck chassis are a known wear and fatigue point on hard-worked units, and a crane whose boom checks out perfectly can still be unsafe if the mounting has worked loose or begun to crack. We assess the mounting and sub-frame as part of the standard scope, not as an extra.
How often does a truck crane need a major inspection?
At the interval set by the relevant standard and equipment class — commonly 5-year or 10-year depending on the equipment type and how hard the crane is worked. Routine and periodic inspections keep it safe in between. We confirm the interval that applies to your specific machine rather than quoting one universal figure, and we can plan the major inspection around your workload so the crane's downtime lands when it costs you least.
Do you inspect the winch and rope?
Yes. The winch, rope, sheaves and hook block are part of the load path and are examined for wear, broken wires, distortion, corrosion and correct termination and spooling. Rope condition in particular degrades progressively, so it is assessed against discard criteria and the finding recorded — a rope that is legal today but close to its limit is worth knowing about before the next big job, not after.
Can you inspect our truck crane on site?
Yes. EWP Australia operates Australia-wide as a mobile field service, so inspections are carried out at your yard or wherever the crane is working rather than taking the truck off the road to reach a depot. To arrange an inspection, call 0416 689 689, or email info@ewpaustralia.com.au.
