Abstract: Wheel chock apparatus including a plurality of wedge members configured to be positioned adjacent to a wheel. Each wedge member comprises a first end and a second opposite end, where a first flexible member is configured to attach to the first ends of each of the plurality of wedge members and a second flexible member is configured to attached to the second opposite ends of each of the plurality of wedge members. The first and second flexible members are configured to adjust a relative distance between the plurality of wedge members. In some examples, the wheel chock apparatus includes a chain and a tightening strap for adjusting the relative distance. In some further examples, the wheel chock apparatus includes locking mechanisms to prevent theft of the machine attached to the wheel and the wheel chock apparatus itself.
