Abstract
A wheel chock system for preventing movement of one or more wheels. The system may include a pair of chocks for clamping onto one or more wheels. The chocks may be connected through a linkage mechanism that can be rotated to draw the chocks together or move the chocks further apart. A handle may be attached to the linkage mechanism for moving the chock system from a blocking position to a released position. The handle may be configured to stand upright such that the chock system can be installed and removed by a user in a standing position without the need to bend or crouch. One embodiment of the chock system may be attachable to two different wheels in a tandem wheel arrangement, whereas another embodiment of the chock system may be configured to clamp onto a single wheel.
