1529977 Trailers K J HEARD 22 Oct 1976 [24 Nov 1975] 47560/75 Heading B7T In a trailer, a towing frame 10 carries front wheels 14 and is pivoted about an upright axis Y to an intermediate structure 40 which itself is connected to a main wheeled frame 4 for pivoting about an axis X fixed in a position transverse to the main frame. The arrangement of pivot axes and wheels allows some weight transfer to the rear wheels of a towing vehicle, which leads to better cornering, and pivoting of the towing frame about an axis longitudinal to the main frame is not possible. Axes X and Y preferably intersect and co-operating bearing surfaces are provided on the towing frame and intermediate structure about the upright axis Y.
