摘要

Wheel chocks for use with loading docks are disclosed herein. In one embodiment, a manual wheel chock configured in accordance with the present disclosure includes a restraint arm pivotally coupled to a carriage that is rollably mounted to a longitudinal guide rail. The restraint arm is rotatable in a first direction to move a wheel stop in front of a wheel of a vehicle parked adjacent the guide rail. The restraint arm is also rotatable in a second direction opposite to the first direction to move the wheel stop away from the vehicle wheel.

1. A wheel chocking system for use at a loading dock, the wheel chocking system comprising:
a guide rail positionable on a parking surface in front of the loading dock, a wheel chock including:
a carriage movably coupled to the guide rail and configured to move fore and aft along a longitudinal axis parallel to the guide rail; anda restraint arm pivotally coupled to the carriage and configured to rotate about a pivot axis extending generally perpendicular to the longitudinal axis, wherein the restraint arm is rotatable in a first direction about the pivot axis to move a wheel stop away from a wheel of a vehicle parked adjacent the guide rail, and wherein the restraint arm is further rotatable in a second direction opposite to the first direction to move the wheel stop in front of the wheel of the vehicle, wherein the guide rail includes a row of teeth, wherein the restraint arm includes a ratchet having a spring-loaded pawl that engages at least one of the teeth when the restraint arm is rotated about the pivot axis in the second direction, and wherein engagement of the teeth by the pawl prevents the restraint arm from moving away from the loading dock along the longitudinal axis.
