20100102287 | LIFTING GEAR - The invention relates to lifting gear having a drive unit ( | 04-29-2010 |
20130069379 | LOAD-RECEIVING MEANS, IN PARTICULAR A HOOK BLOCK OF A LIFTING GEAR - The invention relates to a load-receiving means, in particular a hook block of a lifting gear, comprising a hook having a shaft and a circumferential groove, in which an annular retaining element engages, which annular retaining element is supported on a supporting surface of a suspension element of the load-receiving means, wherein the annular retaining element has the form of a sleeve, which expands starting from the shaft in the direction of the supporting surface. In order to create a secure load-receiving means, in particular a hook block of a lifting gear, the annular retaining element is designed in the form of a conical sleeve in the manner of a truncated cone and has an exterior outer surface, an interior outer surface due to the sleeve shape, an upper annular top surface and a lower annular base surface. | 03-21-2013 |
20130164078 | ARRANGEMENT FOR CONNECTING TWO RAIL SEGMENTS - An arrangement of two rail segments, consisting of at least one mounting element disposed at each rail segment, and of at least one connector in contact with the mounting elements, by means of which the rail segments can be connected to each other at the end faces thereof, wherein each mounting element is attached to the corresponding rail segment by means of a welding seam. In an improved arrangement for connecting rail segments with respect to dynamic loading, at least one end of the welding seam ends in a region on the rail segment outside of the mounting element. | 06-27-2013 |
20140291269 | CRANE, IN PARTICULAR AN OVERHEAD CRANE OR GANTRY CRANE, HAVING AT LEAST ONE CRANE GIRDER - A crane, in particular an overhead crane or gantry crane, comprising at least one crane girder, which extends horizontally and is designed as a trussed girder having an upper run and a lower run. A crane trolley having a lifting device can be moved on the crane girder. The invention further relates to a method for assembling a crane girder, comprising an assembly step for producing the trussed structure of the crane girder. The crane girder includes an adapter on at least one of the two opposite ends, which adapter can be fastened to the upper run and the lower run in such a way that the adapter can be oriented relative to the upper run and the lower run and then the adapter can be welded onto the upper run and the lower run in a desired position. | 10-02-2014 |
20150053636 | CRANE, PARTICULARLY BRIDGE CRANE OR GANTRY CRANE, COMPRISING AT LEAST ONE CRANE GIRDER - The invention relates to a crane, particularly a bridge crane or gantry crane, including at least one crane girder extending horizontally and designed as a truss with a plurality of braces, on which girder a crane trolley with a lifting gear is movable. At least some of the braces have a flat shape. The flat-shaped braces each have a flat main surface that extends in each case transversely to a longitudinal direction of the crane girder. | 02-26-2015 |
