The invention provides a quay crane which comprises a door frame, a rear girder, a front girder, a seaside trapezoid frame, a first stretching part, a supporting frame and a second stretching part, the seaside trapezoid frame is located on the side, close to the front girder, of the rear girder, the lower end of the seaside trapezoid frame is hinged to the rear girder, and the first end of the first stretching part is hinged to the seaside trapezoid frame; when the seaside trapezoid frame is in a vertical state, the front girder is pulled by the first stretching part, the supporting frame is vertically arranged on the side, close to the front girder, of the rear girder, the first end of the second stretching part is connected to the supporting frame, and the second end of the second stretching part is connected to the front girder. And the front crossbeam is pulled by the second stretching part. According to the quay crane, the second stretching part can independently provide pulling force for the front girder, a supporting tool does not need to be arranged between the bottom of the front girder and the door frame, the working procedure during quay crane transportation is simplified, the supporting tool is omitted, and the cost is reduced.
本申请提供一种岸桥,该岸桥包括门框、后大梁、前大梁、海侧梯形架、第一拉伸部、支撑架和第二拉伸部,海侧梯形架位于后大梁靠近前大梁的一侧,且下端铰接于后大梁,第一拉伸部的第一端铰接于海侧梯形架,第一拉伸部的第二端铰接于前大梁,当海侧梯形架处于竖立状态时,利用第一拉伸部牵拉前大梁,支撑架竖立地设置于后大梁靠近前大梁的一侧,第二拉伸部的第一端连接于支撑架,第二拉伸部的第二端连接于前大梁,利用第二拉伸部牵拉前大梁。本申请的岸桥第二拉伸部能够单独地为前大梁提供拉力,无需再设置前大梁的底部与门框之间设置支撑工装,简化了岸桥运输时的工序,省去了支撑工装,降低了成本。
