Lifting mechanisms for truck bodies

A lifting mechanism for truck bodies and the like in combination with a pair of laterally spaced longitudinal stationary frame members, a dump frame including a pair of laterally spaced longitudinal track members pivotally connected to said stationary frame members adjacent one end thereof, said longitudinal track members disposed in a plane immediately above and parallel to the plane of said longitudinal stationary frame members, a rectangular frame stabilizer assembly positioned between and spanning substantially the entire lateral distance between said stationary frame members, an X-brace on said rectangular frame stabilizer assembly and extending the length thereof, a pair of pivot connections connecting the opposite sides of the inner end of said rectangular frame stabilizer assembly to a medial portion of said pair of laterally spaced stationary frame members, a pair of connectors on the opposite sides of the outer end of said rectangular frame stabilizer assembly engaged for sliding movement in said pair of laterally spaced longitudinal track members, the said opposite end of the rectangular frame stabilizer assembly spanning substantially the entire lateral distance between said longitudinal track members, at least one extensible lift cylinder pivotally connected at one end between and in the plane of said stationary frame members and pivotally connected at the opposite end to the outer end of said rectangular frame stabilizer assembly in the plane of the longitudinal track members in the lowered position, said lift cylinder positioned beneath said X-brace of said rectangular frame in the lowered position, whereby upon extension of said extensible lift cylinder said dump frame is moved about its pivot connection with said stationary frame members from a horizontal position to a raised dump position.
