Heavy haul transport refers to the transportation of exceptionally heavy or bulky cargo that exceeds the standard legal limits for size and weight on roadways. This includes any load that surpasses normal weight limits, typically requiring specialized trailers and transportation methods. These loads often include large industrial equipment, heavy machinery, oversized construction materials, or any other substantial items that cannot be easily divided into smaller, lighter segments for transport.

Due to the significant weight and size of these items, heavy haul transport demands meticulous planning and precision. It involves route planning to accommodate the weight and dimensions, acquiring necessary permits, and ensuring the availability of suitable lifting and securing equipment.
