SLAB LIFTING DEVICE AND INSTALLATION METHOD OF SLAB LIFTING DEVICE
To reduce weight of slab lifting device.SOLUTION: A slab lifting device 100 includes a lifting mechanism 50 that can lift slabs 2, an upper holding body 41 that extends in the front-rear direction and holds the lifting mechanism 50, multiple pillars 60A-60D that are attached to the upper holding body 41, traveling mechanisms 21, 26 that are provided below the pillars 60A-60D, and pillar displacement mechanisms 70A-70D that displace the positions of the pillars 60A-60D in the horizontal direction between a first position close to the upper holding body 41 and a second position away from the upper holding body 41, wherein the pillar displacement mechanisms 70A - 70D each include a horizontal connection member 75 that connects the pillars 60A - 60D and the upper holding body 41 in the horizontal direction, and a hinge joint that supports the horizontal connection member 75 rotatably in a horizontal plane with the connection portion between the upper holding body 41 and the horizontal connection member 75 as a fulcrum, and wherein the positions of the pillars 60A to 60D can be displaced between a first position and a second position as the horizontal connection member 75 is rotated.SELECTED DRAWING: Figure 3
【課題】床版揚重装置の重量を軽減させる。【解決手段】床版揚重装置１００は、床版２を吊り上げ可能な揚重機構５０と、前後方向に延在し揚重機構５０を保持する上側保持体４１と、上側保持体４１に取り付けられる複数の支柱６０Ａ～６０Ｄと、支柱６０Ａ～６０Ｄの下方に設けられる走行機構２１，２６と、支柱６０Ａ～６０Ｄの位置を水平方向において上側保持体４１に近接した第１位置と上側保持体４１から離れた第２位置とに変位させる支柱変位機構７０Ａ～７０Ｄと、を備え、支柱変位機構７０Ａ～７０Ｄは、支柱６０Ａ～６０Ｄと上側保持体４１とを水平方向において接続する水平接続部材７５と、上側保持体４１と水平接続部材７５との接続部を支点として水平接続部材７５を水平面内において回動可能に支持するヒンジ継手と、を有し、支柱６０Ａ～６０Ｄの位置は、水平接続部材７５が回動されることに応じて、第１位置と第２位置とに変位可能である。【選択図】図３
