  • Actuate one at the upper end of the receiving tube, for example attached spindle gear can thus the spindle in the receiving tube be moved in or out of this.
  • the two parallel arms pivoted so that the ends the arm-articulated support unit is moved upwards.
  • the receiving tube pivoted because the pivot point of the spindle on the arms due to the pivoting of the arms moves.
  • a hand crank is advantageously provided with which the spindle drive is actuated can be.
  • the support device according to the invention without greater effort can be operated on any construction site. It also exists the possibility of the spindle gear with different over or Equip reductions to convey the lifting of heavy loads To enable actuation of the hand crank.
  • the spindle gear by means of a Electric motor is driven.
  • this Lower two vertical struts with the two arms at the upper ends are pivotally supported between the vertical struts.
  • Such Execution of the lower part represents a structurally simple but nevertheless extremely effective method for the swiveling attachment of the two parallel arms.
  • a Holding device in particular an eyelet
  • a rope or the like are passed through a Beams or other heavy loads to be picked up can.
  • Such an eyelet can thus carry a heavy load like a beam from a position near the ground by the support device according to the invention be raised in such a way that, for example, halfway up on trestles can be applied.
  • the support device can again be turned down until the platform can be brought under the beam.
  • the bar can be turned in by turning up the support device its installation position will be transferred.
  • the invention Possibility that a single user has a heavy load, such as a beam or the like, can be transferred from a position close to the earth into an installation position.
  • the Support device from an operating position to a transport position designed to be collapsible.
  • the transportation costs can be a Support device according to the invention can be drastically reduced.
  • a support device includes lower part 1 and an upper part 2 pivotable relative to this whose upper end in FIG. 1 has a carrying unit 3 attached.
  • the carrying unit 3 in the illustrated embodiment consists of an upper platform 4, which is essentially rectangular in shape, with at the corner points arranged lateral boundaries 5 projecting upward from the platform 4, which are designed, for example, as round bars. Between the side Limitations 5 can be horizontal, for example, on platform 4 running beam or beam. At the bottom of the platform 4 reinforcing ribs 6 are attached.
  • the platform 4 is supported by a short support tube 7, which means two Double tabs 8 is attached to the upper part 2.
  • the upper part 2 includes in addition to the Carrying unit 3 two arms 9 which run substantially parallel to each other and are arranged one above the other. These arms 9 are, for example, as metal struts made of solid material or as a square tube or as a U-profile or the like executed.
  • the arms 9 are gripped a spindle 13 of a spindle drive 14 by means of a further double plate 12 on.
  • the lower part 1 has two vertical struts 15 running parallel to one another, which are also designed as flat bars or square tubes, for example.
  • To the upper end of the vertical struts 15 are the two arms on each other 9 pivotally attached. The two protrude toward this, as can be seen from FIG. 5 Arms 9 between the two vertical struts 15 and are mediated on these Screws 10 and self-locking nuts 11 pivotally attached.
  • a handle 16 is attached to the easier movement of the entire support device is used.
