  • Patent number: 6179542
    Abstract: A kneeling dolly with ramp brake and method of use. Each kneeling dolly with ramp brake comprises a body having a ramp adjacent a wheel well, two front wheels swivellably and retractably attached to the body, and at least one rear wheel. Devices for extending and retracting the front wheels are provided. The instant kneeling dolly with ramp brake may be used singly, in pairs, or in whatever grouping(s) desired. In operation, a vehicle is rolled onto kneeling dollies with ramp brake, until one vehicle wheel is disposed on a respective kneeling dolly with ramp brake. Due to the swivellable attachment of the front and rear wheels, each kneeling dolly with ramp brake is free to travel in any desired direction, and thus the vehicle supported by the kneeling dollies with ramp brake may be pushed in any direction. This flexibility in movement helps relieve congestion and maximize floor space in garages, hangars, etc.
