Ein Antrieb zum Heben und Senken schwerer La- «ten, insbesondere der Tröge von SerUcrecht-Sch.ffshebewerken, wild von mehreren Führungskorpern 1 » sowie ebenfalls mehreren an diesen laufenden Antriebsmitteln2 gebildet. Die Führungskörper 1 sind dabei mindestens in doppelter Anordnung an den Längsseiten der zu bewegenden Last, z. B. des Tragrahmens3 des Schiffshebewerkes, angeordnet und »5 dort als turmartige GebUde ausgeführt, an deren dem Tragrahmen! zugewandten Seite Laufflächen4 für Abstützrollen 5,6 der Querführung und Zahnstangen? für die Ritzel» der Antriebe angebracht sind. Die einzelnen Antriebsmittel 2 werden dabei im ™ wesentlichen von einer Schwinge 9, einem Hebelsystern 10, 11, einer Einstellvorrichtung 13 und e.ner elastischen Abstützung 12 gebildet, wobei das Ritzel8 an der Schwinge 9 drehbar gelagert und die Schwinge 9 selbst über räumlich nachgebende Ge- *5 lenke 14, 15 zum einen am Hebel 10 und zum anderen an der Einstellvorrichtung 13 angeschlossen ist. Die räumlich nachgebenden Gelenke 14, 15 der Schwinge 9 sowie die Verschiebbarkeit der Gelenke 14, is\uf den Achsen,' und *" erlauben der Schwinge9 Drehbewegungen sowohl um die vertikale Symmetrieachse Z als auch um d.e be.den honzontalen Symmetrieachsen X und y der Schwinge 9 so daß die Schwinge 9 und mit ihr auch das Ritzel 8 dem jeweiligen Verlauf des Führungskörpers 1 folgen kann. Das dem Gelenk 15 des Hebels 10 an der Schwinge 9 abgewandte Ende des Hebels 10 ,st über zwei Stangen H an der elastischen Abstutzung 12 gelenkig anschlössen, und es ist d.ese Abstützung 12 als eine doppelwirkende hydraulische Zylinder-Kolbeneinheit, die als vertikale Abstutzung fur die Schwinge 9 am Tragrahmen fungiert, ausgeführt. Mittels dieser Zylinder-Kolbeneinheit kann der Heist A drive for lifting and lowering heavy loads, in particular the troughs of SerUcrecht-Sch.ffshebewerken, wildly formed by several guide bodies 1 and also several drive means 2 running on these. The guide body 1 are at least in duplicate on the longitudinal sides of the load to be moved, for. B. of the support frame3 of the ship lift, arranged and »5 there designed as a tower-like building, on whose the support frame! facing side running surfaces4 for support rollers 5,6 of the transverse guide and racks? for the pinions »of the drives are attached. The individual drive means 2 are thereby formed in the ™ essentially of a rocker 9, a Hebelsystern 10, 11, 13 and an adjusting e.ner elastic support 12, wherein the Ritzel8 on the rocker arm 9 rotatably supported and the rocker arm 9 itself spatially yielding Ge - * 5 link 14, 15 is connected on the one hand to the lever 10 and on the other hand to the adjusting device 13. The spatially yielding joints 14, 15 of the rocker 9 as well as the displaceability of the joints 14, is \ uf the axes' and * "allow the rocker 9 rotary movements both about the vertical axis of symmetry Z and about the horizontal axes of symmetry X and y of the Swing arm 9 so that the swing arm 9 and with it also the pinion 8 can follow the respective course of the guide body 1. The end of the lever 10 facing away from the joint 15 of the lever 10 on the swing arm 9 rests on the elastic support 12 via two rods H articulated, and the support 12 is designed as a double-acting hydraulic cylinder-piston unit, which functions as a vertical support for the rocker 9 on the support frame
