  • Leg adjustment for fifth-wheel trailer lifting/leveling legs
    Patent number: 5527054
    Abstract: An adjustable length leg and foot assembly is incorporated in a lifting/leveling leg for a fifth-wheel trailer. The foot is connected to the lower end of a threaded shaft, which in turn is received at its upper end by a nut welded to a U-shaped bracket on the leg. This enables the foot to be raised and lowered in infinite increments and avoids any need for insertion of boards or shims in making final leveling adjustments.
