Abstract
A folding gooseneck trailer is disclosed having a positioning system for positioning the main bed of the trailer relative to the ground as well as the loading bed, or hitch platform, relative to the main bed and the ground. The loading bed of the trailer is pivotally mounted on the front end of the trailer main bed by a pair of spaced connecting links so that the loading bed can be raised and lowered relative to the main bed. The main bed has wheels at the rear end and, in the raised position, the loading bed holds the front end of the main bed off of the ground when the loading bed is mounted on the fifth wheel of a tractor, as by a king pin. A power mechanism is connected between the loading bed and a clevis plate attached to an elongated sliding element the lower portion of which terminates in a ground engaging foot. The sliding element is received in a channel in the main bed so that the sliding element is constrained to vertical movement in opposite longitudinal directions. The power mechanism is a hydraulic cylinder and piston, and piston extention determines and controls the relative positioning of the sliding element and the main and loading beds, both with respect to one another and to the ground.
