   <Desc/Clms Page number 1> 
 



  Kran mit um eine horizontale Achse drehbarem Ausleger. 



   Die Erfindung behandelt einen Kran mit durch das Hubwerk veränderlicher Ausladung, dessen Auslegerzugorgan je nach Bedarf verkürzt oder verlängert wird. 



   Zur Veränderung der Länge des   Zugorgans   ist dabei die jedesmalige Lösung und Befestigung des Zugorganendes durch einen Arbeiter erforderlich. 



   Dieser Übelstand wird beseitigt, wenn die Länge des Zugorganes selbsttätig ver- änderbar ist. 



   In Fig. 1 und 2 ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt
Am oberen Ende des Auslegerdruckorgans a ist die Hubwerkrolle c angeordnet und eine um den Rollenbolzen d schwingbare Zugstange f. An dieser ist eine   Aasg) eichro) Ie y   befestigt, über die das eigentliche Zugorgan h des Auslegers läuft. 



   Auf dem im Krangestell   m   drehbaren Bolzen i sitzen lose die Hubwerkrolle k und fest die Trommeln l und. auf die sich das Zugorgan h aufwickelt. 



   Auf dem Bolzen i sind ferner befestigt zwei Trommeln n und n1. welche die am unteren Ende mit Gewichten p und p1 versehenen   Seile o und Oj   aufnehmen. Die Trommeln l und 4 sind mit Sperrädern r und r1 verbunden. in die Sperrklinken s und s1 eingreifen. 



   Wenn die Ausladung verringert werden soll, wird der am   Hubseil v   befestigte Anschlagnocken t bis unter den am   Druckorgan   a befestigten Anschlag M gehoben. 



   Durch weiteres Einziehen des   Hubseiles wird   das   Druckorg & n   gehoben und das Zogorgan selbsttätig verkürzt, indem es sich auf die durch die Gewichte p und p1 bewegten Trommeln l und l1 aufwickelt. 



   Wird das Hubseil v nachgelassen, so behält das Zugorgan h die gewollte   Lang\'.   weil die drehbar gelagerten Sperrklinken sunde die Verlängerung verhindern
Wenn die Ausladung vergrössert werden soll, wird der Anschlagnocken t bis an den Anschlag te und etwas darüber hinaus gehoben und alsdann die Sperrklinken s und Si aus den Zahnen der Sperräder r und r1 entfernt. 



   Sodann kann die Ausladung durch Nachlassen des Hubseiles v beliebig verändert werden.

  Crane with boom that can be rotated around a horizontal axis.



   The invention deals with a crane with an outreach that can be changed by the hoisting mechanism and whose boom pulling element is shortened or lengthened as required.



   To change the length of the pulling element, it is necessary for a worker to loosen and fasten the end of the pulling element every time.



   This inconvenience is eliminated when the length of the pulling element can be changed automatically.



   In Fig. 1 and 2, the subject of the invention is shown in an embodiment
At the upper end of the boom pressure member a, the hoist roller c is arranged and a pull rod f that can swing around the roller bolt d. An Aasg) eichro) Ie y is attached to this, over which the actual pulling element h of the boom runs.



   The hoist roller k and the drums l and firmly sit on the bolt i, which is rotatable in the crane frame m. on which the pulling element h winds up.



   Two drums n and n1 are also attached to the bolt i. which hold the ropes o and Oj provided with weights p and p1 at the lower end. The drums l and 4 are connected to ratchet wheels r and r1. engage in pawls s and s1.



   If the overhang is to be reduced, the stop cam t attached to the hoist rope v is raised to below the stop M attached to the pressure element a.



   By further drawing in the hoisting rope, the pressure element is lifted and the pull element is automatically shortened by winding itself onto the drums l and l1, which are moved by the weights p and p1.



   If the hoist rope v is released, the pulling element h retains the desired length. because the rotatable pawls prevent the extension
If the overhang is to be increased, the stop cam t is raised up to the stop te and a little beyond it and then the pawls s and Si are removed from the teeth of the ratchet wheels r and r1.



   The overhang can then be changed as desired by slackening the hoist rope v.
