Definitions

  • the present invention relates to a tiltable lifting platform for motor vehicles, preferably four-wheeled passenger cars.
  • tilting can sometimes be of great benefit, for example when certain work is to be carried out on one side of the vehicle.
  • lifting devices that are not designed as lifting platforms are known, which lift the vehicle on one side.
  • lifting devices such as lifting trucks, which also allow a vehicle to be lifted higher on one side, but which also lead to stability problems for the tilted lifted vehicle leads, which is to be avoided in particular from the point of view of occupational safety.
  • the tires on the non-lifted side are loaded on their narrow outer edge with a force caused by the weight of the vehicle that is far too high, which can damage the tire structure, a circumstance that can be dangerous in particular, but not only with high-speed tires.
  • the prior art attempts to address the problem of stability as well as the excessive loading of the tires remaining on the ground by means of flexing devices which support the wheels in a transverse rail construction between two struts extending transversely to the longitudinal axis of the vehicle in a manner that is formed here by this take up the wheel well and try to dissipate the load over the entire width of the tire.
  • further short struts can be provided between the cross struts perpendicular to the aforementioned transverse struts extending approximately across the vehicle width, which also laterally delimit the receiving tire and support it on its side wall in the event of tilting and thus also absorb part of the load there.
  • a lifting platform onto which a vehicle with preferably all of its wheels arranged one behind the other in the direction of travel drives into a track or on a rail or other wheel mounting device, which the lifting platform preferably has on the left and right.
  • the vehicle can also be picked up by the lifting platform, with all wheels of the vehicle preferably arranged one behind the other in the direction of travel, in a track or on a rail or other wheel mounting device, for example like a transport fork.
  • At least one track or rail or other wheel mounting device has a lifting mechanism (lifting element), such as a scissor lifting mechanism - e.g. operated by means of hydraulics, e.g. oil hydraulics - by means of which it and thus also the vehicle on it can be lifted on the corresponding side.
  • a lifting mechanism such as a scissor lifting mechanism - e.g. operated by means of hydraulics, e.g. oil hydraulics - by means of which it and thus also the vehicle on it can be lifted on the corresponding side.
  • Harmful squatting, bending, kneeling or twisting when working on the vehicle can be avoided as far as possible.
  • the roof of a vehicle - e.g. for polishing the paint - can be reached much better by one person on the side to which the vehicle is tilted. Conversely, on the other, (more) raised side of the vehicle, its side surfaces are more accessible.
  • the track or rail or other wheel mounting device on which the wheels lying one behind the other on the side of the vehicle to be raised are located, with a
  • a scissor lifting mechanism operated, for example, by means of hydraulics, e.g.
  • the lifting scissors itself both with the ground (or a floor panel or the like) as well as with the track or rail or the other Wheel mounting device is articulated.
  • This articulated connection is preferably made by means of a double joint in the manner of a swinging door hinge, as is also used with swinging doors, such as western saloon doors, whereby this double joint can be used both on the floor and also on the track or rail or other wheel mounting device.
  • it can also only be provided for an articulated connection on the ground or only for an articulated connection on the track or rail or other wheel mounting device.
  • an articulated connection in particular a double-articulated connection in the manner of a swinging door hinge, twisting or bending of the lifting scissors can be prevented when the lifting platform is raised on one side.
  • the lifting mechanism is monitored on one side to ensure that it is in a specific position, preferably approximately completely lowered to the ground.
  • the lifting platform can also have a monitoring device that monitors the lifting mechanism on one side and the lifting mechanism on the other side for compliance with a maximum lift difference in order to prevent the vehicle from tipping over to the side by appropriate control or regulation of the lift mechanisms if this difference is exceeded be able.
  • a synchronous lift or a synchronous lowering of the lifting mechanisms can also be provided if a certain difference in lift is maintained between the two sides of the vehicle, which can easily be done by means of appropriate control or regulation of the drives of the lifting mechanisms - for example by means of a so-called electronic shaft, such as those available on the market is available — can be realized. In this way, work safety can also be taken into account.
