To provide a connection beam for a crane and a mounting method for the connection beam for the crane that are able to reduce a load applied to an upper revolving body when turning the upper revolving body while running a self-propelled carriage, capable of supporting a counterweight, in parallel.SOLUTION: A connection beam 60 includes: a slider 62 having a carriage connection portion 621 that is connected to a self-propelled carriage 50; and a beam body 61 having a revolving-body connection portion 610A that is connected to an upper revolving body 11. The beam body 61 supports the slider 62 movably in a longitudinal direction while restraining the slider in a lateral direction of the upper revolving body 11 so as to allow the self-propelled carriage 50 to move in the longitudinal direction relative to the upper revolving body 11 by traveling of the self-propelled carriage 50 in a direction including the longitudinal direction.SELECTED DRAWING: Figure 3

    【課題】カウンタウエイトを支持可能な自走式台車を並走させながら上部旋回体を旋回させる際に上部旋回体に掛かる負荷を低減することが可能なクレーンの連結ビームおよびクレーンの連結ビームの取付方法を提供する。【解決手段】連結ビーム60は、自走台車50に連結される台車連結部621を有するスライダ62と、上部旋回体11に連結される旋回体連結部610Aを有するビーム本体61とを備える。ビーム本体61は、自走台車50の前後方向を含む方向への走行によって自走台車50が上部旋回体11に対して前後方向に相対移動することを可能とするように、スライダ62を上部旋回体11の左右方向において拘束しながら前後方向に沿って移動可能に支持する。【選択図】図3
