    Kettenpr & fmaschme.   



   Kranketten u. dgl. werden meist vor ihrer Verwendung durch eine Probelast   geprüft.   Dies geschieht in eigenen Kettenprüfmaschinen, in welchen die Ketten bei mehrmaligem Einspannen in Stücken von   5-10     1n   Länge geprüft werden. Bekanntlich kann man Ketten auch fortlaufend prüfen, indem die zu prüfende Kette von einem gebremst ablaufenden Kettenrade   dauernd gleichmässig   abgezogen wird. 



   Gegenstand der Erfindung ist eine Kettenprüfmaschine, bei welcher die zu prüfende Kette von einem Kettenrade, Rolle od. dgl. über eine bewegliche Rolle zu einem zweiten Kettenrad, Rolle od. dgl.

    Chain test & fmaschme.



   Crane chains u. The like. Are usually checked by a test load before they are used. This is done in our own chain testing machines, in which the chains are tested several times in pieces of 5-10 1n in length. It is well known that chains can also be tested continuously by continuously pulling the chain to be tested from a chain wheel that is slowed down.



   The subject of the invention is a chain testing machine in which the chain to be tested moves from a sprocket, roller or the like via a movable roller to a second sprocket, roller or the like.
 EMI1.1
 device with a constant tensile force, corresponding to twice the test load of the single-strand chain. In order to be able to continuously check when the chain is stretched, the incoming chain strand has a slower speed than the outgoing one. B. by
 EMI1.2
 
The drawing shows an example of the execution of the chain testing machine. The chain K is tensioned from the sprocket ssi via a movable roller R2 to the second sprocket R3, which is rotated by the chain.

   A suitable tensioning device W is provided with the movable roller R2

PATENT CLAIMS:
1. Kettenprüfmasehine, in which the chain is pulled under tension between two fixed chain wheels, characterized in that a movably mounted third chain roller under the influence of a tensioning device is arranged between the two chain wheels.
