Group transportation vehicles are vehicles for the transport in the single structure, and as part of trains. Transport trucks can be divided into two groups: general and specialized.
The design of general purpose vehicles designed to transport a very wide range of bulk and unit (elementary) cargo, pallets, containers, light duty. Typically, these include cars with conventional free-board and airborne platforms, including those with side platforms, covered with an awning.
Referred to specialized vehicles main transport destination, but equipped for the carriage of goods of a given type, for self loading and self-discharge. The design of special-purpose vehicles should:
maximum use of the rated load capacity due to the associated body cargo density, and consistency of the body structure and physical properties of the geometry of the goods or their packaging;
the prevention or reduction of external influences on the cargo in the least, it provides a mechanical safety, and changes in the physical-chemical (or biological) properties within that do not violate the requirements of keeping quality
