Definitions

  • the invention relates to a loading harness with a loading boom that can be swiveled between two posts in a lmm bearing, which carries a first auxiliary stroke at the upper end of an extension extending beyond the fittings of the main lift, the block fitting carrying the upper loading block and the guide disk rotatable about the loading axis and its guide disk and Rope sheaves of the upper loading block are arranged eccentrically to the axis of rotation of the block fitting on the latter, the distance of the block fitting of the first auxiliary lift from the fittings of the main lift being at least so large that when the lower loading block and loading hook of the first auxiliary lift are raised and in an approximately vertical position of the loading boom the lower edge of the loading hook is clear of the fittings on the main lift.
  • the object of the invention is therefore to remedy this.
  • a block fitting of a second auxiliary lift by means of a second extension of the loading boom is fixedly or only rotatably connected to the block fitting of the first auxiliary lift rotatable about the loading boom axis in such a way that when the loading boom swings through through the post level, the second auxiliary lift is also rotated into the other work area, and that the second auxiliary lift, when the lower loading block with the loading hook is raised, in an approximately vertical position of the loading boom with the lower edge of its loading hook, preferably releases from the block fitting of the first auxiliary lifting stroke.
  • the block fitting of the second auxiliary lift is arranged such that it can be rotated to a limited extent by stopper by approximately +/- 15 ° about the axis of the second loading boom extension.
  • This possibility that the block fitting of the second auxiliary lift can rotate about + / 15 ° about the axis of the second loading boom extension is advantageous when it is necessary that the two auxiliary lifts pull obliquely against each other.
  • a limitation of the possibility of rotation is also necessary to ensure that when the loading boom swings through the post level, the second auxiliary lift is also rotated into the other working area.
  • the second auxiliary stroke can work independently of the first auxiliary stroke and the main stroke and, if the connection is appropriately dimensioned, also simultaneously.
