A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. A pair of locking jaws are pivotally connected to the top plate and pivotal between a closed configuration where the pair of locking jaws block passage of a kingpin out of the throat and the locking jaws are held primarily in compression and an open configuration where a kingpin may pass into and out of the throat. Each of the pair of locking jaws has an engagement surface adapted to engage a kingpin positioned in the throat when the pair of locking jaws are in the closed configuration. A locking member is movably attached to the top plate and a mechanism urges the locking member into engagement with the pair of locking jaws when the pair of locking jaws are in the closed configuration.
