A heavy hauler is a very large transporter to move too large a load too large for unattended road trips and special permissions.
The heavy hauler usually consists of heavy tractor units and multi-axled flatbed flatbed trailers. Some trailers may have wheels that can be controlled independently, and some trailers may be coupled by one or more tractor units on the train.
Self-propelled modular transporters, some featuring a dozen and more self-steering steers with a number of rubber tires to spread the load, are increasingly being produced. The combined ability and self-propelled heavy hauler to carry an unusual 100 ton load.

In some cases severe heavens are designed and constructed to move a particular load on a one-time or short-term basis. An example is a self-propelled antenna transporter for the ALMA radio telescope project, a 130-ton 28-wheeled rigid vehicle designed to carry and place a 115 tonne telescope radio antenna up the mountain to a height of 5000 m (16,500 ft). Rolling bridge trailers are also other specialist heavy carriers, especially for transporting large power transformers.
General loads transferred by heavy carriers under escort on the highway include giant boilers and pressure vessels used in chemical industry, industrial plants, prefabricated parts for construction projects, giant power transformers, turbines, and homes (generally made of wood).
The term "heavy carrier" may also be used to refer to off-road dump trucks and ore carriers used in mining and construction with a capacity of up to 400 tonnes, or aircraft that have been specially constructed for transporting heavy materials.
There are several shipbuilding companies that use SPMT to carry parts of ships and build ships in China. They have reduced the millions of dollars cost consumed to transport loads using a gantry crane. It is also the first company to use SPMT to build ships in China.
