To provide a crane with a suspended-type electric hoisting machine for facilitating the attachment/detachment of a width adjustment member to adjust the width between a pair of trolley frames.SOLUTION: A crane comprises a suspended-type electric hoisting machine with the electric hoisting machine suspended from an electric trolley via a hanging pin. The electric trolley comprises wheels attached to each of a pair of trolley frames and the hanging pin pivotally installed between the trolley frames. The electric hoisting machine comprises a hoisting machine frame suspended from the hanging pin and a hoisting machine drum. Multiple width adjustment members to adjust the width between the hoisting machine frames and the trolley frames are arranged on the hanging pin between the trolley frames and the hoisting machine frames. The width adjustment member comprises a semicircular notch along an outer peripheral surface of the hanging pin and fastening member inserting holes. The fastening member inserting holes are provided to be displaced to one side with respect to the center in a width direction of the width adjustment members. The width adjustment member is fixed to the trolley frames with the fastening members inserted into the fastening member inserting holes.SELECTED DRAWING: Figure 5

    【課題】一対のトロリフレーム間の幅を調整する幅調整部材の脱着を容易にする。【解決手段】クレーンは、電動トロリに吊りピンを介して懸垂された電動巻上機を有する懸垂型の電動巻上機を備える。電動トロリは、一対のトロリフレームのそれぞれに取り付けられたホイールと、トロリフレーム間に軸架された吊りピンを備え、電動巻上機は、吊りピンに懸垂される巻上機フレームと、巻上機ドラムを備える。トロリフレームと巻上機フレームとの間の吊りピンの部分には、巻上機フレームとトロリフレームとの間の幅を調整する複数枚の幅調整部材を配設する。この幅調整部材は、吊りピンの外周面に沿う半円弧状切欠きと、締結部材挿入孔を備え、この締結部材挿入孔は、幅調整部材の幅方向の中心に対し一方側に偏位させて設けられ、幅調整部材は締結部材挿入孔に挿入された締結部材によりトロリフレームに固定される。【選択図】図5
