Cargo transportation is mostly carried out without exceeding the allowed size. At the same time, some structures or mechanisms due to the specificity of construction or assembly cannot be divided into smaller parts. When at least one dimension of a cargo (length, width, height) exceeds the permissible value, the cargo is considered to be oversized. For the transportation of such goods special vehicles and equipment are used. Depending on the size of the cargo and the specifics of the transit countries, we select the optimal route, order the necessary authorizations or escort. If necessary, we combine several transportation modes, part of the route assigning to the railways.
