Abstract: A lift bed highway trailer adapted to be coupled to a tractor to transport heavy loads through use of pallet frame units that can be quickly picked up and discharged at any point, including an improved power actuated mechanism in the trailer gooseneck structure and in the suspension subframe for positively locking the liftable bed in the raised transport position.
Abstract: A lift bed highway trailer adapted to be coupled to a tractor to transport heavy loads through use of pallet frame units that can be quickly picked up and discharged at any point, wherein provision is made in the trailer gooseneck structure for safely dissipating the kinetic energy of the pallet frame unit through resistance of friction and gravity in event of an emergency stop.
