Patent number: 6045122Abstract: 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.Type: GrantFiled: February 9, 1998Date of Patent: April 4, 2000Inventor: Manuel Torres

Patent number: 4920596Abstract: 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.Type: GrantFiled: March 2, 1989Date of Patent: May 1, 1990Inventor: Michael L. Stevens

Patent number: 4920597Abstract: 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.Type: GrantFiled: November 9, 1988Date of Patent: May 1, 1990Assignee: Hein-Werner CorporationInventor: Harold F. Hamilton

Patent number: 4901980Abstract: Portable car hoist convertible to a trailer which has wheels for towing a vehicle. The hoist includes a trailer with a suspension, a wheel assembly, a base frame assembly, a liftable platform assembly, and a lift apparatus. A foldable ramp, a platform, and extension channels support a vehicle to be lifted, and a chock assembly retains the vehicle on the platform. A safety latch prevents accidental lowering of the platform assembly.Type: GrantFiled: April 29, 1987Date of Patent: February 20, 1990Assignee: Johnson Industries, Inc.Inventor: N. Larry Hansen

Patent number: 4895347Abstract: 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.Type: GrantFiled: November 21, 1988Date of Patent: January 23, 1990Inventor: Jerome J. Anderson

Patent number: 4886243Abstract: 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.Type: GrantFiled: October 26, 1988Date of Patent: December 12, 1989Inventor: Christopher J. Trumbull

Patent number: RE34889Abstract: A lightweight, high strength, portable vehicle service ramp capable of being used by aerodynamic vehicles and heavy trucks. The ramp is solid on all sides with integrated handles on the sides and rear. The base and rear of the structure are covered with a corrosive-and-wear resistant material. 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.Type: GrantFiled: July 21, 1993Date of Patent: April 4, 1995Inventors: William W. Fogarty, Phillip M. Friday
