What is a Dolly Trailer?

Asset Finance

A dolly is an unpowered trailer which can be attached to trucks, tractors and road trains. The dollies themselves don’t carry a load but are used to support a semi-trailer or similar haulage unit. The main types of dollies are Converter and Low-Loader.

Converter dollies are commonly used in road trains as part of a combination. It has a drawbar for its forward connection and pivots vertically. It allows multiple trailers to be attached forming the roadtrain configuration.

Low-loader dollies are available which use a kingpin, not a drawbar coupling so that heavy cargo doesn’t overload the wheels of the truck.

A dolly can be removed from a road train at an assembly yard once the truck reaches heavily populated areas. A long vehicle yellow and black sign is required on the rear bumper of these over-length vehicles.

Road Authorities

Every state and territory in Australia have a road authority which controls the length, weight and roads over-sized vehicles may use.

New South Wales - Transport, Roads and Maritime Services

A national body oversees the design and use of all new and used, locally manufactured and imported heavy vehicles. The Australian Design Rules is in its third edition and comes under the federal government’s Department of Infrastructure and Regional Development.

The Heavy Vehicle National Law and regulations were passed and commenced in February 2014 in all states and territories except the Northern Territory and Western Australia. The body regulates vehicles over 4.5 tonnes gross.
