RAIL LOADING PROP AND OTHER DEVICES OF OVERHEAD SLEWING CRANE GIRDER

摘要

The present invention relates to a A-shaped pole (10) as a support bar compensating curve load where hoisting load is intensively applied to an upper flange (16) of a high-capacity overhead slewing crane equipped with a transverse rail (21) in the center line of a girder (100), while the structure of the high-capacity overhead slewing crane equipped with the transverse rail is stable in a cross-sectional structure where the load is applied. An H-shaped stiffener (17) is welded alongside the pole for adding a cross-sectional performance in the structure where the load is uniformly distributed to a box web (14) and a lower flange (15). The H-shaped stiffener is anchored to a seismic hook (22) of a trolley (101) from the impact of earthquake vibration and act as a safety barrier above the girder (100).;COPYRIGHT KIPO 2014
