In the seventies one experienced the supply of construction sites as well! The Hanomag Henschel completed the semi-trailer with the rear tipper trailer, which had a contemporary wood planking. The traditional model builders have used this proven chassis to create a historic tipper from new forms, which today brings a lot of zeitgeist into the 1:87 scale. With the semi-trailer in the now fourth rear-tipper version Wiking has a truck trailer running into the program, which became popular in the late sixties. The suspension trains, which were particularly common in the building materials sector and which had until then shaped the construction sites in the supplier sector, were increasingly falling behindthe semi-trailers were simply more maneuverable and just as resilient. In this model the rear-side trough is arranged flexibly. The new form dump trailer has a back-tilt function and fits seamlessly into the wide range of construction site vehicles, which Wiking has so far miniaturized.
