Abstract: A parking device attachable to one end of a vehicle understructure for use in parking the vehicle, includes a carriage and coupling mechanism which permits the carriage to move either to a retracted position or to a deployed vertically-spaced position, and a parking wheel having a pivotal mechanism which permits the parking wheel to be pivoted either to a folded, substantially horizontal position or to a deployed, substantially vertical position. A drive is coupled to the carriage and to the parking wheel and is effective, when the carriage is in its retracted position and the parking wheel is in its folded position, first to move the parking wheel to its deployed position and then to move the carriage to its deployed position lowering the parking wheel into engagement with the ground and raising the respective end of the vehicle off the ground.
