Definitions

  • this object is achieved in that the hitches consist of hooks with outwardly directed hook tines and that the Coupling part of two articulated on a connected to the hoist rope holding part pivotally mounted equal length handlebars is formed at their free ends Wear eyelets and provided with a detachable, this spreading spreader are.
  • the ballast plates can be easily characterized take and settle that the ends of the spread arms on both sides the hook placed on the line connecting the hook, the spreader in the manner is solved by lifting the holding part, the ends of the handlebars to run under gravity so that the eyelets run into the hook and be caught by them as it were.
  • This allows the ballast plates without hand-hanging with the scissors-like lifting couple the Hubseils closing handlebars.
  • ballast plates By lifting the ballast plates With the hoist rope and rockers of the tower, ballast plates can be ballasted on the box and on top of each other and in reverse order remove again.
  • rollers are arranged on both sides of the eyelets on the handlebars, which allow a collision of the handlebars with good guidance.
  • the links may consist of mutually parallel struts whose free ends are connected by bolts to form the eyelets.
  • the extended bolt ends can be axle journals for supporting the rollers form.
  • ballast plates to their stacking on each other will continue characterized by having guides for the ends of the scissors Handlebars and centering devices when depositing towards each other for formation edge straight stack are provided.
  • the hooks are each arranged in troughs of the ballast plate.
  • These troughs can be provided with guides for the ends of the handlebars be.
  • the troughs are parallel to the connecting line of the hooks extending sides, which form guides for the roller units.
  • the sides of the hollows towards the flat trough bottom bevelled so that the roller units center themselves in the troughs and when lifting the scissors-type links on the connecting line, the hooks to run.
  • the rectangular to the line connecting the hooks extending outer sides of the wells are beveled and spaced from each other, the distance of the spread ends of the handlebars corresponds.
  • the Kniehebellenker 27 are based on not shown Stops the handlebars 20, 21 from, so that the links 20, 21 by the Kniehebellenker 27 are held in their spread position.
  • the Kniehebellenker 27 are in the range of their pivot axes 25, 26 extend with this outward provided angularly connected levers 28, with which the Kniehebellenker 27 by pivoting in the direction of arrows A from their Kochtot Vietnamese ein let solve.
  • the links 20, 21 are made, as shown in Fig. 7 can be seen is, from each of 2 spaced parallel struts 30. This Struts are connected at the ends by horizontally extending bolts to eyelets. The bolts are laterally extended beyond the struts 30 so that these journals form for receiving the rollers 24.
  • the ballast plates 6 are formed so that they are without special manual Actuate the scissor-shaped arms 20, 21 and detach from them to let. Furthermore, the ballast plates 6 are provided with facilities to these Align so precisely when stacking that edge-to-edge stacks form.
  • the ballast plates have an approximately circular section shape in plan view, wherein the curve part formed by obtuse angiomine straight sections is.
  • the ballast plates 6 are on their Upper sides with recesses 32 provided. In the recesses are hooks 33 fastened, the hook tines 34 each facing outward.
  • the recesses 32 are provided with bevelled side walls 35, the towards the bottom of the recesses 32 toward one another.
  • bevelled side walls 35 the towards the bottom of the recesses 32 toward one another.
  • the distances the side walls and the bevels chosen so that in the recesses 32 lowered with rollers 24 provided ends of the links 20, 21 in the recesses transverse to the hook 33 connecting connecting line 38th be centered.
  • the rear side walls 39 of the recesses 32 are at the bottom 36th provided with bevels 39, the distance about the distance of the rollers 24 in the expanded state of the handlebar 20, 21 corresponds.
  • ballast plates 6 For centering the ballast plates 6 in the direction of the connecting line 38 of the hook 33 are lateral trapezoidal cross-section beads 40 at the lateral areas the ballast plates 6 provided in the complementary recesses grip the undersides of the ballast plates.
  • ballast plates 6 For alignment transverse to the connecting line 38 are on the straight sides of the Ballast plates 6 stirrups 41 provided. These stirrups are with the ends their Schwenkel anchored to the tops of the ballast plates 6. The thigh are then bent twice at right angles, so that perpendicular to the Ballast plates resulting sections 42, horizontal sections 43 and vertical downwardly facing portions 44 result, by web portions 45 with each other are connected. Below the stirrups are the ballast plates 6 on their front sides provided with recesses 46. For centered settling the tower piece 4 as far as tilted, that the rear walls 47 of the recesses easily support the front vertically rising portions of the legs of the stirrups. The backs 47 thus slide on the vertical sections 42 until the plates are mutually aligned with each other.
