In road transport, a road, road, air freight or other transport infrastructure to transmit an oversized load (or overweight load) on a specific part of a freight truck that exceeds a standard or ordinary legal size and / or weight limits or water transport. It can be called special shipping or heavy and oversized shipping in Europe. Load per axle can be limit. However, a load that exceeds the per axle limits, but exceeds the general weight limits, is considered overweight. Examples of overweight / overweight loads include construction machinery (cranes, front loaders, holders, etc.), pre-built houses, containers, building elements (bridge beams, generators, windmill propellers, rocket stages, industrial equipment).
Legal dimensions and weights differ between countries and regions within a country. A vehicle that exceeds the legal dimensions usually requires a special permit that requires extra charges for the overweight / overweight vehicle to legally travel on the road. The clearance usually specifies a route the freight must take and the dates and times the freight can go.
When a load cannot be disassembled into portable units without exceeding the limitations in terms of size and / or mass, it is classified as an abnormal load. Another definition can be summarized as follows: Abnormal indivisible load ('AIL') is a load that cannot be divided into two or more loads for transport (on roads). [1] Also, bulk cargo is used to describe the load that cannot be loaded into any ocean container or that is too large for air cargo.
The CMR Convention (Convention on the Convention on the International Transport of Goods by Road), framed by any road transport, [2] deals with various legal issues regarding the transport of cargo, mainly by trucks by road.
