To provide an auxiliary tool for assembling a crane capable of facilitating the positioning of a connector pin and shortening the assembling time while eliminating high-place work for performing insertion work of a connector pin when assembling the crane.SOLUTION: The auxiliary tool for assembling a crane is used for assembling a crane which includes a jib formed by connecting a plurality of partial jibs in a longitudinal direction in that the plurality of partial jibs are protruded toward a back side and a ventral side of end parts at which they are connected to each other and a back side connector and a ventral side connector connected to each other by insertion of a connector pin. The auxiliary tool for assembling the crane includes a supporting member having a pair of guide surfaces, which abut on the partial jibs in a suspended state from the outside in the width direction, and a support surface, which supports the ventral side of the partial jibs, a base for holding a lower end part of the supporting member to be self-standable, and a connector pin insertion machine that is provided on the supporting member and moves in a protruding direction of the supporting member so as to insert the connector pin into the ventral side connector.SELECTED DRAWING: Figure 5

    【課題】本発明は、クレーンの立組でのコネクタピン挿入作業の高所作業をなくすとともに、コネクタピンの位置決めを容易化し、組立時間を短縮できるクレーン立組用補助治具の提供を目的とする。【解決手段】本発明は、複数のパーシャルジブを長手方向に接続して形成されるジブを備え、複数のパーシャルジブが、互いに接続される側の端部の背側及び腹側に突設され、コネクタピンが挿入されることにより互いに接続される背側コネクタ及び腹側コネクタを有するクレーンを組み立てるためのクレーン立組用補助治具であって、懸垂状態のパーシャルジブに幅方向外側から当接する一対のガイド面及びパーシャルジブの腹側を支持する支持面を有する支持部材と、支持部材の下端部を自立可能に保持する基台と、支持部材に配設され、支持部材の立設方向に移動し腹側コネクタにコネクタピンを挿入するコネクタピン挿入機とを備える。【選択図】図5
