To provide a truck frame elevating device capable of easily securing safe and excellent working environment before and after assembling or disassembling a truck frame of a railway vehicle and an axle while highly accurately raising/lowering the truck frame.SOLUTION: A truck frame elevating device 10 incudes positioning pins 311 formed to be engaged with positioning holes DW11 of a truck frame DW from below and raises/lowers the truck frame engaged with the positioning pins between a raised position above a work floor surface and a lowered position. The truck frame elevating device includes an elevating device main body part 1 installed below the work floor surface and an elevating part 2 guided by the elevating device main body part to be raised and lowered between the raised position and a stored position. An upper end part of the elevating part includes a positioning mechanism 3 having a positioning pin mounting part 31 mounted with the positioning pin and a support part 32 supporting the positioning pin to be stored by turning the positioning pin mounting part upside down. When the positioning pin is stored and the elevating part is lowered to the stored position, an upper end surface of the positioning mechanism forms a flat surface with the work floor surface.SELECTED DRAWING: Figure 4

    【課題】鉄道車両における台車枠を精度よく昇降させると共に、台車枠と輪軸とを組付け又は分解する前後において安全で良好な作業環境を簡単に確保できる台車枠昇降装置を提供する。【解決手段】台車枠DWの位置決め孔DW11に下方から係合可能に形成された位置決めピン311を備え、位置決めピンに係合した台車枠を、作業床面より上方の上昇位置と下降位置との間で昇降させる台車枠昇降装置10である。作業床面の下方に設置された昇降装置本体部1と、昇降装置本体部に案内されて上昇位置と格納位置との間を昇降する昇降部2とを備え、昇降部の上端部には、位置決めピンが装着された位置決めピン装着部31と、位置決めピン装着部を上下反転して位置決めピンを収納可能に支持する支持部32とを有する位置決め機構3を備え、位置決め機構の上端面は、位置決めピンを収納させ昇降部を格納位置に下降させたときに、作業床面との間で平坦面を形成する。【選択図】 図4
