How to calculate the metre tonne rating of your Vehicle Loading Crane?
Vehicle loading cranes are rated in metre tonnes. This tends to cause some confusion amongst users. It is particularly important to understand the size requirements of your crane, because licensing requirements in Australia for vehicle loading cranes is determined by the rated capacity of the vehicle loading crane.
Vehicle loading cranes rated at 10 metre tonnes or above require a CV license to operate them.
So how is this rating determined?
To calculate the metre tonne rating of your crane, you need to:
- Refer to your crane’s load chart (located on the boom of the crane).
- Determine from the load chart the MAXIMUM LOAD (in Tonnes) your crane can lift at each particular RADIUS (In Metres).
- Multiply these 2 numbers together (Metres X Tonnes)
- If the answer is equal to or greater than 10, then you require a CV license to operate your Vehicle Loading Crane.
Example: Look at the load chart below from a knuckle boom crane.
Therefore: 3.1 metres x 5.2 tonne = 16.12 metre tonnes
This crane requires a High Risk Work (CV) license to operate it.
What are the mobile crane licences? (C2, C6, C1, C0)
A slewing mobile crane means a mobile crane incorporating a boom jib that is capable of being slewed. This excludes front end loader, backhoe, excavator and other earthmoving equipment when configured for crane operation.
There are four classes of slewing mobile cranes each with a different capacity:
- up to 20 tonnes (C2) – incorporating CN & CV classes
- up to 60 tonnes (C6) – incorporating C2, CN & CV classes
- up to 100 tonnes (C1) – incorporating C6, C2, CN & CV classes
- over 100 tonnes capacity (C0) – incorporating C1, C6, C2, CN & CV classes
If a slewing telehandler is fitted with a boom and/or jib with a hoist rope and/or hook block, a C2, C6, C1 or C0 high risk work licence is required, dependent on the telehandler’s rated capacity.

What is Dogging?
load, which includes:
- calculating safe angles for slings or chains
- selecting the type of sling or chain to be used
- selecting the correct method to secure the load
- selecting the safe method to lift or turn the load
- checking the conditions of lifting gear for wear and tear.
A DG licence is also required by anyone directing the operator of a crane or hoist in the movement of a load when the load is out of the view of the operator.
