<p>The floor element of the caravan is connected to the upper surface of a chassis frame consisting of transverse-and longitudinal supports. The chassis is connected to an all-round profiled frame, which corresponds to the external contours of the caravan, and to which the floor and sides of the body are fastened. The profiled frame is divided parallel to or along a wheel vertical axis, and the angled sections may be fastened to each other. The frame has a bridge-like section to accommodate the trailer wheels, which are sprung on trailing arms pivoting in a centre cross-tube.</p> |
