Device for increasing the loading capacity of towing vehicles so as to receive semi-trailers for transporting heavy loads

摘要

To the towing vehicle 1 there is hitched, about a vertical axis 7, the swan-neck end of a bissel-type truck 4 with guiding wheels 5. To the bissel-type truck 4 there is hitched at 12 the front end 10 of a semi-trailer 11 with a large load capacity. The towing vehicle 1 carries, towards the rear, a tilting bolt 16 designed to engage guide members secured to the chassis of the bissel-type truck 4 so as to eliminate the articulation about the vertical axis 7. The device then behaves like an articulated two-element trailer which elements are, on the one hand, the tractor 1 / bissel-type truck 4 and, on the other hand, the semi-trailer 11. The invention makes it possible to tow semi-trailers with a large load capacity at the front. IMAGE
