 wo Schienenhub und Weg des Trieblings längs der Zahnstange vollkommen identische Grössen sind. 



  Überdies muss bei Anwendung einer Zahnstange für das an ihr emporsteigende Huborgan unbedingt eine besondere Führung vorgesehen sein, die bei Betätigung der Winde durch das von der Last herrührende Kippmoment gegen die Zahnstange gepresst wird, so dass beim Wandern des Trieblings bedeutende   Reibungswiderstände   auftreten. Demgegenüber tritt bei Betätigung des Gleishebers gemäss der Erfindung nur die Reibung im Drehzapfen des Hubhebels auf. 



   PATENT-ANSPRÜCHE :
1. Gleisheber mit einer mit Fussplatte versehenen, einen Zahnbogen tragenden Konsole, welche im Mittel zum Zahnbogen den doppelwangigen,   am Zahnbogen seitlich geführten Hubhebellagert, dadurch   gekennzeichnet, dass der einarmige Hubhebel (H) zwischen der an seinem Ende vorgesehenen Hub-

 where the rail stroke and the path of the pinion along the rack are completely identical.



  In addition, when a rack is used, a special guide must be provided for the lifting element rising up on it, which is pressed against the rack when the winch is actuated by the tilting moment resulting from the load, so that significant frictional resistance occurs when the pinion wanders. In contrast, when the track lifter according to the invention is operated, only the friction occurs in the pivot of the lifting lever.



   PATENT CLAIMS:
1. Track lifter with a bracket provided with a footplate, carrying a dental arch which, in the middle of the dental arch, supports the double-cheeked lifting lever guided laterally on the dental arch, characterized in that the one-armed lifting lever (H) is positioned between the lifting lever provided at its end.

 forms, which rises together with the lifting lever on the arch of the console when the track lifter is actuated.

Claims (1)

2. Momentauslosung zum Gleisheber nach Anspruch 1, dadurch gekennzeichnet, dass die das Sperrad haltende, am Hubhebel ortsfest gelagerte Klinke (Ko) durch Betätigung des Antriebshebels über den normalen Bedienungsweg hinaus aus den Zähnen des Sperrades aushebbar ist und so den Zahntrieb freigibt. 2. Moment release for the track lifter according to claim 1, characterized in that the pawl (Ko) holding the ratchet wheel and fixedly mounted on the lifting lever can be lifted out of the teeth of the ratchet wheel by actuating the drive lever via the normal operating path and thus releases the pinion. 3. Momentauslösung zum Gleisheber nach Anspruch 2, dadurch gekennzeichnet, dass die Betätigung des Antriebshebels (A) über den normalen Bedienungsweg hinaus erst durch Ausheben der Mitnehmerklinke (Kb) möglich ist. 3. Momentary release for the track lifter according to claim 2, characterized in that the actuation of the drive lever (A) via the normal operating path is only possible by lifting the driver pawl (Kb).
