Abstract
A wheel chock has a body with a shell and filled core construction capable of supporting high chocking loads while being relatively lightweight and portable. The chock includes walls sized and shaped to support large-diameter wheels such as wheels of large haul vehicles and mining trucks. The chock can be sized proportional to the radius of the wheel to be retained or based on the radius of curvature of a wall configured to primarily support the outer surface of the wheel. The chock can have a cut off or flattened toe or front surface that reduces weight and helps to ensure that the entire chock is load-bearing when in a chocking position. The chock can also have a flattened top surface to support the outer surface of a tire that deforms around the chock while it is being retained by the chock.
