Definitions

  • the present invention concerns hoisting devices, and in particular a so called free wheel hoisting device.
  • Such free wheel hoisting devices are especially used for the hoisting of vehicles in connection with repairs, trouble shooting, inspection and similar. With their help it is possible to hoist a vehicle at least at one wheel axle in such a way, that the wheels at the axle ends at the same time can rotate freely.
  • This type of free wheel hoisting devices is commonly used in auto inspection facilities, where vehicles are hoisted for the examination of the state of the wheel suspension, steering mechanisms, wheel bearings and other important parts for safe road operation.
  • the purpose of the present invention is to eliminate the above problems. This objective is achieved by a free wheel hoisting device according to the claims, in which what is charac ⁇ teristic of the invention also becomes evident.
  • fig. 1 is a perspective side view of a free wheel hoisting device according to the invention
  • f ig. 2 is a side view of a free wheel hoi sting device 2 according to the invention, in a lowered position,
  • fig. 3 i s a side view according to fig. 2 showing the free wheel hoisting device in an elevated position
  • the free wheel hoisting device 1 which is shown in fig. 1 , comprises a supporting framework 2 in the form of two parallel arranged square bars 3 , 4 , in which suspension elements 5 , 6 are displaceably arranged.
  • suspension elements 5 , 6 are supposed to bear on to the edges of a lubricating or inspection pit, where there are guide rails (not shown) , on which rails rolers 7 run, which are in an unloadable way attached to the suspension elements 5, 6.
  • a jack 8 Approximately in the mid- length of the parallel arranged square bars 3 , 4, there is provided a jack 8 and this jack, which in the shown embodiment is hydraulic, is driven by a hydraulic power supply 9 for the raising and lowering.
  • a lifting beam 10 which is rais ed and lowered by means of the jack 8
  • the lifting beam 10 there are two extension elements 11 , 12 displaceably mounted and the extension elements 11, 12 have at there extremities holder fittings 13, for the sake of adapting to appropriate places on the axle, or similar, to be raised.
  • an arm system being of the following structure:
  • fork elements 14, 15 pivotably attached to the supporting framework 2, one on each side of the jack 8. They are connected by means of a pair of cog wheel segments 16, 17 in a gear engagement, which, when one of the fork elements 14, 15 is being pivoted, cause the other segment to follow to the same extent.
  • the portions of the fork elements 14, 15 that are distal to the cog wheel segments 16, 17, are equipped with trunnions 18, 19 extending in longitudinal grooves 20, 21, which are parallel with the plane of the lifting beam 10 and which are formed in projections 22 which are welded at the underside of the lifting beam 10.
  • the fork elements 14, 15 there is an arm 23 pivotably attached to one arm of a fork element 15, as well as to a connection piece 24 attached to the lifting beam 10.
  • the arm 23, serves to help one of the fork elements 15 to pivot and through the cog wheel segments 16, 17 to pivot the other fork element 14 as well, while the transfer of the load unbalance of the lifting beam 10 occurs through the projections 22 and the trunnions 18, 19, which is then counteracted by the force transfer of the cog wheel segments 16, 17.
  • the present invention provides both a simple and safe hoisting device, eliminating the initially posed problems with the known devices.
  • the invention can, per se, be varied regarding details, but such variations are supposed to be encompassed by the scope of the invention, as they are defined in the appended patent claims.

Abstract

Dispositif de levage permettant de soulever une voiture ou similaire et comprenant un châssis de support rectangulaire (2), un palonnier (10), et, situé entre ces deux éléments, un vérin (8). Afin de maintenir le palonnier (10) dans une position parallèle au châssis de support (2), le dispositif est pourvu de deux fourches (14, 15) pivotantes s'étendant entre le châssis de support (2) et le palonnier (10); ces deux fourches sont en contact, l'une avec l'autre, par l'intermédiaire d'éléments de transmission des forces (16, 17) faisant pivoter lesdites fourches (14, 15) en synchronisme, mais dans des directions opposées, dans un plan parallèle à l'axe longitudinal du châssis de support rectangulaire (2).
