DepotOps report: How much can I load?
Made 29 Sept 2026, 5:53 pm at depotops.com.au/payload. An estimate from the figures entered, not a weighbridge certificate, permit or legal advice.
The most you can carry is the lowest legal or rated limit, less the empty weight of the rig. This works it out for semitrailers, B-doubles and road trains under the HVNL.
Rules checked 30 Sept 2026 against NHVR general mass limits information sheet (1 Aug 2026), Mass, Dimension and Loading National Regulation (in force) and Main Roads WA prime mover, trailer combinations operating conditions. Official pages are watched weekly for changes.
Leave blank to use the general HVNL limit.
Weigh the rig empty, with a full fuel tank, the driver and the gear it always carries. That is the tare that counts.
You can load up to
28.00 t
Set by the legal gross limit of 43.5 t, less 15.50 t empty weight.
| Group | Limit |
|---|---|
| Steer | 6.0 t |
| Drive tandem | 17.0 t |
| Trailer tri-axle | 21.0 t |
