Self-propelled modular transporters (SPMTs) are heavy haulers used to transport bulky goods. You are likely to see them in use in construction sites.

Many governments use them to construct roads and bridges. You can also find SPMTs in shipyards. The transporters are made of dozens of wheels that are controlled by a control panel or computer.

One modular trailer can transport tons of heavy loads. However, it takes several modular trailers to move some loads from one section to another.

Some construction sections and equipment cannot be carried with one trailer. The quality, versatility, capacity, and durability of SPMTs vary across brands. Keep reading to discover the top manufacturers of the best modular trailers in the world.
