LIFTING APPARATUS
To facilitate the improvement of workability and weight reduction of an apparatus by earning the lifting margin.SOLUTION: A lifting apparatus 2 is configured to be provided with a travel girder 3, a traversing device 5 placed to be freely traveled on the travel girder 3, and a chain block 30 locked to the traversing device 5, the chain block 30 being offset in the width direction with respect to the longitudinal direction of the travel girder 3 so as to be arranged on the front side of the traversing device 5. The traversing device 5 is provided with a main body 10, upper rollers 11A and 11B rotating in contact with an upper surface 3A of the travel girder 3, front side support roller 12A and 12B rotating in contact with the lower end of a lateral surface 3B on the front side of the travel girder 3, and rear side support rollers 13A and 13B which rotate in contact with an upper end of a lateral surface 3C on a rear side of the travel girder 3, the rollers being provided on the main body 10. Each of the rollers 11A, 11B, 12A, 12B, 13A, and 13B support an unbalanced load at the time of lifting a heavy object.SELECTED DRAWING: Figure 2
【課題】吊り上げ代を稼いで作業性の向上と装置の軽量化を図る。【解決手段】吊上器２は、走行桁３と、この走行桁３に走行自在に載置される横行装置５と、横行装置５に係止されるチェーンブロック３０とを備えて構成され、このチェーンブロック３０を、走行桁３の長手方向に対して幅方向にずらすように、横行装置５の前方側に配置するようにしている。横行装置５は、本体１０と、この本体１０上部に設けられ、走行桁３の上面３Ａに当接して転動する上ローラ１１Ａ、１１Ｂと、走行桁３の前側の側面３Ｂの下端部に当接して転動する前側支持ローラ１２Ａ、１２Ｂと、走行桁３の後側の側面３Ｃの上端部に当接して転動する後側支持ローラ１３Ａ、１３Ｂとを備えている。これら各ローラ１１Ａ、１１Ｂ、１２Ａ、１２Ｂ、１３Ａ、１３Ｂにより、重量物吊り上げ時の偏荷重を支持するようになっている。【選択図】図２
