Inclined Plane Lifter Patents (Class 254/88)
  • Patent number: 6045122
    Abstract: A safety vehicle lift having a base, a lifting assembly, a drive mechanism, a handle, and a ramp. The base is made of flat rigid construction which may be in one or two sections and may be of solid or grated construction. When in two sections, the sections may be permanently abutted with a hinge or may be temporarily abutted with conventional locking mechanisms. The base contains retractable wheels. The base is wider than the structures supported by the base. A drive mechanism is made up of a jackscrew passing through a threaded cross brace. When the jackscrew is turned manually or mechanically, there is a raising or lowering of the support platform. The lift is provided with a ramp having side walls and leading from the level of the base to the level of the support base. The ramp may be of solid or grated construction. The lift has less weight and equivalent strength compared to prior lifts, thus improving mobility. As the base is grated, the lift may be used on a wide variety of surfaces.

  • Patent number: 5863026
    Abstract: An improved vehicle ramp is formed to eliminate interference between the vehicle spoilers and the ramp by extending the ramp when assembled such that the ramp has a lesser angled or sloped inclined surface. The improved vehicle ramp is further formed to eliminate ramp sliding as the vehicle is driven onto and up the ramp. Finally, the improved vehicle ramp eliminates knifing into the ground under loading. The improved vehicle ramp includes a base ramp with a base plate under its vertical edge. The improved vehicle ramp further includes a ramp extension secured to the base of the base ramp incline, and a ramp transition secured between the ramp extension and base ramp for providing a lesser sloped incline with a gradual entrance angle. The ramp extension, ramp transition, and base plate from two improved vehicle ramps are packageable in a compact nature for shipping, display and storage.

The incline and top plane area of the ramp are covered with non-skid material. A wheel stop is provided in a configuration to reduce kickback. The internal construction is a system of cross members running longitudinally and transversely to provide weight bearing capability. Ramp design provides for movement, storage and transporting efficiency.

  • Patent number: 5001798
    Abstract: A drive-on vehicle supporting arrangement for use with a floor anchor system includes a pair of parallel, spaced vehicle supporting treadways, each of which includes vehicle support stands secured to floor anchors to affix the support stand to the floor and clamps to connect to the undercarriage of a vehicle. Removable treadways are positioned between front and rear vehicle support stands. Additionally, a front treadway extends forwardly from the front vehicle support stand and a rear treadway extends rearwardly from the rear vehicle support stand and are supported by treadway support stands. A ramp leads to the rear treadway so that the repairman can drive a vehicle onto the treadway surface, elevate the vehicle, if necessary, by portable jacks and secure the vehicle atop the support stands. Thereafter, the treadways may be removed for clear access to the underside of the vehicle to facilitate repair.

  • Patent number: 5000423
    Abstract: A lift for raising or tilting a small vehicle such as a riding lawn mower is disclosed including first and second ramps. The ramps each include an angled portion connected to a horizontal portion in turn connected to a vertical portion. The ramps are held by legs which extend from the vertical portion and which in the preferred form are removably pivotably mounted for ease of assembly and storage. T-shaped levers are pivotally mounted to the upper free ends of the vertical portions and generally include a first bar having a first end pivotably mounted to the ramps and a second bar having a first end conntected to the first bar intermediate its ends. In the most preferred form, the levers are pivotably mounted to the ramps by a cylindrical bar rotatably and slideably received in collars formed on the levers and ramps, with the cylindrical bar also holding the ramps in a spaced, parallel relation. Straps interconnect the free ends of the first bars of the levers with the vehicle.

  • Patent number: 4920596
    Abstract: A two level car wheel elevating device for elevating the front wheel (146) of a car having a bumper assembly (117) and comprising, first (100), second (102), third (104), and a fourth (106) top level wheel tread segments joined together to form a continuous wheel ramp surface over which the car wheel (146) can travel from ground level (142) to the fourth top level wheel tread segment (106) with a minimum of discontinuities, a pair of vertically positioned sidewalls (108, 110, and 112) positioned on either side of the wheel ramp surface and firmly secured to the wheel ramp surface to support the weight of the front or back car wheels on the wheel ramp surface, the top perimeters (136) of the sidewalls extending above the wheel ramp surface a substantially constant distance to reduce the chance of said front wheel of the car from rolling off the side of the wheel elevating device.

  • Patent number: 4895347
    Abstract: A starting ramp assembly is intended for use with a wheeled vehicle for enhancing the starting ablility of the vehicle and for moving with the vehicle in a forward direction after the vehicle is clear thereof. The assembly includes a wedge-shaped ramp which has a generally rectangular ground-contacting base, including a frame which has plural, box-like regions formed therein. Plural base pads are mounted to the frame and are spring-biased to a position where the pads extend below the level of the base and provide a skid surface when the vehicle is clear of the ramp, the pads being shiftable upwards relative to the frame when the vehicle is on the ramp, providing a slip-resistant contact between the frame and the ground. The ramp includes an inclined, vehicle-support surface which extends upwards from one end of the base and an upright member extending between the other end of the base and vehicle-support surface. A length of chain is connected to the other end of the ramp and is attachable to the vehicle.

  • Patent number: 4886243
    Abstract: A hydraulically elevatable ramp apparatus is set forth wherein a ramp formed of an upper and lower portion with a pivotal hinge joining the two portions secured to a hydraulic jack at a forwardmost position. The ramp at a first lowered position accepts vehicles of diminished ground clearance wherein the vehicle is thereafter elevated to a second position whereupon the lower hinged portion is automatically repositioned upon elevation of the upper portion. The jack is formed with a resilient pad to insure a non-slip arrangement upon elevating a vehicle to a second elevated position.
