Definitions

  • the invention relates to a lifting platform for motor vehicles with a central lifting plunger, at the upper end of which a U-shaped cross member is fastened, which has flat longitudinal members with support plates attached to the free ends of its vertical legs
  • vehicle supports Due to the excess width of the vehicle supports, motor vehicles of different sizes and track widths can be raised on their body floor without adjusting the side members. These vehicle supports can also be arranged in a longitudinally displaceable manner on the side members, which enables a motor vehicle to be raised on the wheels.
  • the object of the invention is to provide a lifting platform of the type specified, which enables the additional lifting of a motor vehicle on the body floor without problems.
  • the integrated arrangement of the lifting cylinders in the vertical legs of the cross member means that no additional space is required for the lifting devices.
  • the provision of the hydraulic distributor for the two lifting cylinders ensures precise synchronous operation from the fully retracted starting position to the end position of the maximum stroke, whereby minimum stroke differences in the end positions inevitably compensate for each other. Additional mechanical interlocks can also be provided for locking the lifting cylinders in their end positions.
  • a recess is formed in each of the longitudinal members, in which the travel rail with the body supports is at least partially received when the lifting cylinder is retracted.
  • each of the lifting cylinders is expediently fastened with its upper end via an intermediate piece at the upper end of the square legs and with its lower end recessed in a recess in the cross member, which is a sufficient height of the legs Stroke guaranteed.
  • the bending stiffness of the side members of the lift, with which the vehicles are lifted on the wheels, is increased improved according to an expedient embodiment in that the longitudinal beams have the cross-sectional shape of a flat trough with a flat cover plate made of sheet steel and are completely filled with a rigid foam.
  • Reliable long-term operation and also a relatively simple complete assembly are favored by a special embodiment of the invention, in which the hydraulic or electrical supply lines for the lifting cylinders run in a hollow profile or tube extending synchronously with the central lifting ram.
  • the inherently rigid longitudinal beams can have at least one end of a folding support adjustable in length and possibly the spirit level of a spirit level, which the setting and control of a precisely horizontal position for performing z. B. surveying allows.
  • a device for adjusting and horizontally aligning the side members at the connection point of the side member with the upper end of the vertical leg of the cross member can also be provided.
  • a hydraulic lifting ram 3 is permanently mounted in a tub 2 cast with concrete 1.
  • a cross member 5 is fastened, which consists of a horizontal flat support bar 6 and two rectangular hollow legs 7, 8.
  • a hydraulic lifting cylinder 9, 10 mounted, by means of an upper intermediate piece 11, 12, the position of the lifting cylinder is chosen so that the upper end faces of the cylinders with the side members 13, 14 are flush with the upper ends of the vertical legs.
  • cutouts are provided in the central part, into which the support plates 17, 18 attached to the upper ends of the reciprocating pistons 15, 16 can be at least partially received.
  • These support plates have a soft, elastic padding layer to prevent damage to the body floor when lifting.
  • the longitudinal beams 13, 14 form rails and have a flat trough-shaped cross section with a flat top plate. They consist of sheet steel and are completely filled with a rigid foam.
  • a tube 23 is also fastened in the tub 2, in which the supply lines 24 for the lifting cylinders 9, 10 and possibly also electrical cables for measuring devices and luminous elements 25 run.
  • the upper end of the tube 23 is attached to the horizontal flat bar 6 of the cross member 5, so that the tube 23 executes a synchronous movement with the lifting piston 4.
  • a folding support 26 is attached to the end of each longitudinal beam 13, 14, which - in the illustrated state runs parallel below the longitudinal beam and can be swung out into a vertical support position if required .
  • Setting and checking the position of the side members is simplified by arranging a spirit level at one or both ends of each side member 13, 14.
  • an adjustment device can also be provided due to the high bending stiffness of the side members, which is in the area of the connection of the side member is arranged with the respective vertical legs of the cross member. In order to be able to adjust the side member, the screw fastening of the side member to the vertical leg is loosened and tightened again after the adjustment process.
