PROBLEM TO BE SOLVED: To allow a shuttle boom to be stably moved (slid) by improving rectilinearity of the shuttle boom and allow occurence of noise to be suppressed.SOLUTION: In a quay crane, in which a running device 13 is arranged below a leg part structure 11, a shuttle boom 2 that can be slid in a traverse direction in the leg part structure 11 or a frame-type structure 22 provided above the leg part structure, a plurality of rails 7 are arranged in the shuttle boom 2 at predetermined intervals in a running direction of the quay crane and the rails 7 are held respectively by supporting wheels 5 that have brims on both left and right sides like pulleys, a holding member 24 that contacts an inside face and an outside face of each rail 7 is provided in the leg part structure 11 or the frame type structure 22 and the rails 7 so that the rails 7 are prevented from meandering by the holding member 24.
【課題】シャトルブームの直進性を向上させてシャトルブームの移動(スライド)を安定的に行い、かつ騒音の発生を抑制し得るようにする。【解決手段】脚部構造物11の下部に走行装置13を設け、前記脚部構造物11又は前記脚部構造物の上部に設けた枠型構造物22に横行方向にスライド可能なシャトルブーム2を設け、該シャトルブーム2に岸壁クレーンの走行方向に所定の間隔を隔てて複数のレール7を設け、かつ、前記レール7を夫々滑車のように左右両側に鍔のある支持車輪5によって担持する岸壁クレーンにおいて、前記脚部構造物11又は前記枠型構造物22に各レール7の内側面と外側面に当接する保持部材24を設け、該保持部材24によって前記レール7の蛇行を防止する。【選択図】図1
