ABSTRACT:
A wheel chock for tandem wheels including upper and lower spaced apart wedge members sized and configured for wedging engagement with facing surfaces of the tandem wheels. A threaded rod joins the upper and lower wedge members. The threaded rod is connected to each of the upper and lower wedge members such that rotation of the rod in a first prescribed direction causes translational movement of each of the upper and lower wedge members along the rod and toward one another, and such that rotation of the rod in a second prescribed direction causes translational movement of each of the upper and lower wedge members along the rod and away from one another. At least one of the upper and lower wedge members includes a longitudinal bore formed therein, a transverse bore formed therein and intersecting the longitudinal bore, and a pivot nut having a body and a threaded nut bore formed therethrough. The body is disposed within the transverse bore such that the threaded nut bore is positioned at an intersection of the longitudinal and transverse bores. A portion of the rod is disposed in the longitudinal bore and threadedly engages the pivot nut.
