ABSTRACT:
A system for adjusting a sliding undercarriage along a length of a semitrailer and adjusting a sliding fifth wheel along a length of a tractor. The tractor used for pulling the semitrailer. The system is used for balancing a load on the semitrailer, adjusting the truck and semitrailer turning radius and for operator convenience. The sliding undercarriage and sliding fifth wheel may be adjusted from the cab of the tractor when the tractor and trailer are in operation. The system includes a control panel under computer control. The control panel is received inside the cab of the tractor and electrically connected to a first electric motor and first gear box mounted on the tractor. The first gear box drives a pair of parallel screws threadably attached to a pair of ball screws. The ball screws are secured to the fifth wheel of the tractor. When the first gear box is actuated, the screws attached to the fifth wheel move the fifth wheel forward and aft on the tractor. The control panel is also electrically connected to a second electric motor and second gear box mounted on the trailer. The second gear box drives a pair of elongated parallel screws threadably attached to a pair of ball screws. The ball screws are secured to the sliding undercarriage mounted underneath the semitrailer. When the second gear box is actuated, the screws move the sliding undercarriage forward and aft on the trailer. The control box is designed for receiving satellite communications and audio communications for adjusting trailer weight requirements when traveling interstate.
