Definitions

  • the invention relates to a lifting device for lifting objects, in particular of vehicles, with a Schohubech and a 1925hubech, wherein to reduce the necessary measuring and control means for the entire lifting device, which may consist of a Haupthubech and a 1925hubech, only a single hydraulic unit with corresponding controls can be used.
  • US 5 024 141 A discloses a lifting device with a sensor arrangement in which the synchronous course of the cylinder with pulse generator and sensors is ensured, and the hydraulic cylinders are individually controlled.
  • WO 95/11189 A1 discloses a lifting device, wherein two bypass valves are provided, which are controllable by a control unit.
  • the sensors measure an extension length of the cylinders.
  • US Pat. No. 6,189,432 B1 discloses a lifting device with sensors that measure a lifting height. Synchronization is ensured by a control unit that controls a bypass valve.
  • the main lifting gear and the additional lifting gear are driven in cascade, resulting in a total lifting height which is greater than the lifting heights of the individual lifting units.
  • the main lift is raised and then extended the additional hoist.
  • Commercially available lifting platforms have two rails, which are accessible by a vehicle. In each case, a scissor lift is used for each rail, for example, to ensure sufficient accessibility to the vehicle floor. Between the two Scissor lifts are no mechanical fasteners provided. Since these scissor lifts are independently raised, therefore, there is a technical need to bring the lifting height of the two rails, (left and right rail) permanently to the same level and to hold.
  • the object of the invention is to provide a lifting device for lifting objects, in particular vehicles, which manages with as few measuring means and control means.
  • the lifting device for lifting objects, in particular of vehicles, has at least two main lifting units and at least two additional lifting units on.

  • the control unit is a hydraulic control unit having a flow divider and two bypass valves, wherein with the control unit alternatively a synchronization control of the Haupthubajien or visahubüen is feasible.
  • control unit may be a control and / or regulating unit and the main actuators and additional actuators may be designed as seat valves.
  • the lifting units can be hydraulically operated. It may be in the lifting units or in the lifting device to underground stages with punches, to pillar lifts, possibly also with telescopic actuation, and / or swing lifts.

  • This can ensure that the individual lifting units can not be operated simultaneously and thus the risk of error detection of a synchronization by the control unit, although the lifting units perform uneven lifting movements is excluded.
  • a bypass valve of the respective higher main lift unit and / or additional lift unit can be temporarily transferred into an open state. This results in the advantage that minor differences in stroke between the respective lifting units of a running rail with respect to. The other rail can be compensated without interrupting the lifting movement of the lift.
  • a stroke difference between the lifting units can be compensated in a particularly simple manner, wherein this compensation is faster than when only the bypass valve of each higher lifting unit is opened for a limited time.
