Abstract
A monorail carriage for use with H-beams wherein carriage rollers mounted on frame-cantilevered shafts remain in continuing full-length running engagement with the monorail beam flanges throughout varying downward load deflection of such flanges. Rockable roller bearing elements at opposite ends of each roller include one which is spring loaded so as to force translation or displacement of the roller in response to flange deflection so as to maintain such full-length contact of the roller with the beam flange, although with attendant shift of the center of pressure lengthwise of the roller on the track flange.
Claims10
A monorail crane carriage adapted to run on the lower web-supported flanges of a generally horizontal H-beam, said carriage including a frame supported by and supporting load-bearing rollers mounted respectively on coaligned opposing support shafts which are frame-cantilevered to project inboard transversely in relation to the beam web, said rollers each comprising annular tread means with relatively inboard and outboard portions having cylindrical tread surfaces in running engagement with an H-beam lower flange, and separate antifriction bearing means for each roller rotatively supporting the respective inboard and outboard portions of said tread means on a shaft, one such separate bearing means comprising resiliently carriage load-compressed support means interposed between the associated tread means portion and the shaft permitting rocking of such tread means portion accompanied by translational yielding thereof in relation to the shaft for maintaining running contact with the flange of the tread surface of such portion over its full length as flange deflection changes with varying carriage load.
