Excess mass and dimension operations

Excess mass movements

The Guideline for Operation of Excess Mass (Form 11) is an alternate means of legally complying when the mass of a vehicle exceeds the mass requirements of the Heavy Vehicle (Mass, Dimension and Loading) National Regulation 2013.

The guideline establishes the vehicle and mass limits and conditions of operation of excess mass special purpose vehicles to 40t and vehicles carrying an indivisible item to 59.5t.

The guideline conditions include route restrictions on the state-controlled road network. Approval for travel on local government roads is the responsibility of the Approved Heavy Haulage Operator.

The guideline also forms the foundation for the issue of excess mass permits, thereby providing for consistent and uniform excess mass permit management throughout Queensland.

The Guideline for Operation of Excess Mass (Form 11) is available from the NHVR Transitional Notices page.

Approved Heavy Haulage Operator (AHHO)

To operate an excess mass vehicle in Queensland an operator is required to register as an AHHO. Applicants must provide information such as company details and a list of persons authorised to sign on behalf of the company for permits. The AHHO application form is available below and applications should be faxed to 07 3832 4984.

Authority to Operate (ATO)

Each special purpose vehicle or prime mover operating in the excess mass scheme is required to obtain an ATO. The ATO will identify the vehicle as being eligible to participate in the scheme and will provide compliance personnel with data on the permitted operating mass of the vehicle.

The information required includes:

  • vehicle description and approved operating masses
  • supervised weighing of the vehicle
  • for a prime mover, proof of manufacturer's maximum load rating for axle groups, gross vehicle mass and maximum gross combination mass.

The ATO application form is available below and applications should be faxed to 07 3832 4984.

Excess mass permit operations

Excess mass permits will be required for the movement of vehicle above guideline limits. The guideline forms the basis for excess mass permits. Permits will exempt vehicles from a limit in the guideline and impose additional conditions necessary for the safe movement of the vehicle.

Some specified classes of heavy mobile cranes and special purpose vehicles are eligible for excess mass permits of extended duration and radius when they participate in the Intelligent Access Program.

Conditions of operation for heavy mobile cranes and special purpose vehicles are located on the Excess mass and dimension conditions page.

Excess dimension movements

Excess dimension travel is based on the requirements of the Guideline for Excess Dimension in Queensland (Form 4), available from the NHVR Transitional Notices page. Travel in excess of 4.6m width requires a Letter of No Objection issued by the Department of Transport and Main Roads.

An excess dimension permit is required for travel over 5.5m wide and/or 5.0m high. These permits are issued by the Queensland Police Service.
