A wheel assembly is for mobilizing a construction vehicle upon a base surface and includes a frame connected with the vehicle and configured to pivot about a first axis. At least one and preferably two axles are connected with the frame and configured to pivot respectively about a second axis and a third axis, the second and third axes each extending generally perpendicularly with respect to the first axis. Each axle has a longitudinal centerline extending generally perpendicularly with respect to the second axis. Two wheels are preferably connected with each axle so as to rotate generally about each axle centerline. When the wheels are disposed generally upon the base surface, the wheels roll with respect to the surface so as to at least partially mobilize the vehicle. Further, angular displacement of the frame and the axle about the second axis move the wheels within two perpendicular vertical planes.
