Abstract
Abstract A low platform trailer having three segments; a hitch platform, a flat bed for the main load, and an intermediate, or goose-neck section between the hitch platform and the flat bed. The segments are united with joints that pivot and which are driven by separate power rams. The hitch platform and goose-neck section are unfolded down for easy loading and unloading of the flat bed. After loading, the hitch platform and goose-neck section are folded up for lifting of the loaded flat bed to the traveling position and attachment of the hitch platform to a tractor truck. The goose-neck section forms an angle of about 30* with the horizontal so that small rubber-tired and tracked machines may be readily driven up or down the goose-neck section to or from the flat bed.

Claim 1
Independent Claim
184 words
A flat bed trailer, comprising: a. a hitch platform; b. a flat bed; c. an intermediate section; d. means for pivotally joining the rear of the hitch platform to the front of the intermediate section, said means including a first pivot pin adjacent to top surffaces of the hitch platform and the intermediate section; e. means for pivotally joining the rear of the intermediate section to the front of the flat bed, said means including a second pivot pin adjacent to bottom surfaces of the intermediate section and the flat bed; f. means for independently locking both joining means in predetermined positions, said locking means iNcluding a first pin positioned generally below the first pivot pin, and a second pin positioned generally above the second pivot pin; g. a first source of mechanical energy interconnected between the hitch platform and the intermediate section for bidirectionally rotating the hitch platform with respect to the intermediate section; and h. a second source of mechanical energy interconnected between the intermediate section and the flat bed for bi-directionally rotating the intermediate section with respect to the flat bed.
