Schmitz Cargobull: dolly trailers reduce carbon emissions by quarter

2021/08/24 at 8:12 AM

The dolly trailers are gaining popularity among the European hauliers. Schmitz Cargobull, the Germany-based manufacturer of trailers and semi-trailers, has already delivered 500 units. According to it, the solution is able to make road transport greener by reducing carbon emissions by 25 per cent.

Schmitz Cargobull’s twin-axle dolly trailers are based on the company’s modular system. The vehicles are equipped with variable air suspension, an established ROTOS running gear system and Multi Ride Height system as well as a range of drawbar options. As a result, the dolly trailer can be used for all coupling positions. Moreover, it has a swivelling fifth wheel for an optimum ride response. The solution from Schmitz Cargobull is suitable for two combinations of ultra-long trucks, 25.25 and 31.5 metres long. Due to the lack of joint EU regulations, the dolly trailers are certified only in Scandinavia. As for today, they are under scrutiny for getting approval in Spain and the Netherlands.

The dolly trailer is a crucial component of the EcoDuo trailer combination of the ultra-long heavy goods vehicles. It can easily be split between two tractor units at border points or in specific areas. In comparison to a conventional HGV, a tractor unit and one trailer with a 40-tonne total tractor-trailer weight, the EcoDuo concept offers several advantages. For instance, it allows the hauliers to consume less fuel per transported tonne and reduce CO2 emissions by 25 per cent. Furthermore, the solution contributes to tackling the issue related to the lack of truck drivers since just one driver can transport two trailers with one tractor unit over long distances.
