I went through production technology for making a main model, a matrix and the manufacture of two panels. The client did not mount solid pages on his trailers – two side and one for the ceiling, and a tarpaulin cover. Covering the entire load compartment with hard pages will give even better fuel consumption results. An individual solution for the particular type of trailer can be found in view of the dimensions of this panel. Panel dimensions – height 1,7 m, width 1,39 m and bulge of the volume – 45 cm. It is mounted on a metal frame. The two panels are tested in real conditions. The savings achieved in fuel consumption (diesel) are from 1 L to 1,5 L per 100 km. In intensive journeys and accumulation of large kilometers, a good return can be expected.
