Determining the Metre Tonne Rating for Your Vehicle Loading Crane
Vehicle loading cranes are classified by their metre tonne rating, which can often cause confusion among users. Understanding the size requirements of your crane is crucial, as licensing regulations in Australia for vehicle loading cranes are based on their rated capacity.
Vehicle loading cranes with a rating of 10 metre tonnes or higher necessitate a CV license for operation.
So, how is this rating calculated?
To determine the metre tonne rating of your crane, follow these steps:
- Consult your crane’s load chart, typically located on the crane’s boom.
- Identify the MAXIMUM LOAD (in Tonnes) that your crane can lift at various RADIUS points (in Metres), as specified in the load chart.
- Multiply these two numbers together (Metres x Tonnes).
- If the result is equal to or greater than 10, a CV license is required to operate your Vehicle Loading Crane. For example, let’s consider the load chart below for a knuckle boom 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 particular crane necessitates a High Risk Work (CV) license for operation.
What are the licences for mobile cranes? (C2, C6, C1, C0)
A slewing mobile crane is a mobile crane equipped with a boom jib that can be slewed. This classification excludes front end loaders, backhoes, excavators, and other earthmoving equipment when configured for crane operations.
There are four categories of slewing mobile cranes, each with its own capacity:
- Up to 20 tonnes (C2) – includes CN and CV classes.
- Up to 60 tonnes (C6) – includes C2, CN, and CV classes.
- Up to 100 tonnes (C1) – includes C6, C2, CN, and CV classes.
- Over 100 tonnes capacity (C0) – includes C1, C6, C2, CN, and CV classes.
If a slewing telehandler is equipped with a boom and/or jib with a hoist rope and/or hook block, a high-risk work licence of C2, C6, C1, or C0 is required, depending on the telehandler’s rated capacity.
