PROBLEM TO BE SOLVED: To provide a quay crane capable of supporting a slide type boom stably even if leg opening deformation occurs in a leg structure, and starting cargo handling operation quickly by suppressing the swing of the slide type boom which occurs immediately after the traveling of the quay crane.SOLUTION: A quay crane 1 comprises: a beam member 13 fixed to an upper end of a leg structure 4 and extending in a travel direction y of the quay crane 1; a suspension structure 6 suspended from the beam member 13; and a slide type boom 7 supported on the suspension structure 6 and slidable in a traverse direction x of the quay crane 1. The suspension structure 6 comprises a pair of arm parts 11 separating in the travel direction y and extending in a vertical direction, and arm connection parts 12 extending in the travel direction y for connecting each of the arm parts 11 to the leg structure 4. Each of the arm parts 11, the arm connection parts 12, and the leg structure 4 are connected by pin members extending in the traverse direction x.

    【課題】脚構造体に脚開き変形が生じても安定してスライド式ブームを支持できるとともに、岸壁クレーンの走行直後に生じるスライド式ブームの揺動を抑制して、荷役作業を迅速に開始することのできる岸壁クレーンを提供する。【解決手段】脚構造体4の上端に固定されて岸壁クレーン1の走行方向yに延びる梁部材13と、この梁部材13に吊持される懸架構造体6と、この懸架構造体6に支持され岸壁クレーン1の横行方向xにスライド可能なスライド式ブーム7とを備え、懸架構造体6が走行方向yに離間して上下方向に延びる一対のアーム部11と、それぞれのアーム部11を脚構造体4に連結する走行方向yに延びるアーム連結部12とを有し、それぞれのアーム部11とアーム連結部12と脚構造体4が横行方向xに延びるピン部材により連結される。【選択図】図3
