These Tractor Units, introduced late 1999, haul a wide range of semi-trailers connected by a fifth-wheel hitch system, mounted just forward of its rear-most wheels. This Tractor model has 8 tyres on 3 axles and known as a 6-wheeler or 2+6. The Tractor unit carries a share of total laden capacity and provides the semi-trailer with air-brake and electrical services, connected by flexible brake air-lines and multi-core power cables called “Suzies”. In addition to these our chassis incorporates a mesh looking walk-way for safe access. The picture shows the rear view of both the 2+4 and 2+6 variants.
