ABSTRACT:
A wheel blocking device includes a pressure foot which is attached to one end of a pressure foot arm. The other end of the pressure foot arm is pivotally connected to either the frame or an axle of the vehicle. One end of an actuator is connected to the pressure foot arm and the other end is connected to either the frame or an axle of the vehicle. When the actuator actuates, the pressure foot is forced into engagement with a tire of the vehicle. The pressure foot indents the tire to a predetermined degree, thereby providing a positive mechanical lock to prevent rotation of the tire. A control system allows the vehicle's driver to actuate the wheel blocking device while seated in the vehicle's cab.
