The invention discloses a shore crane. The shore crane comprises a front girder; the front girder comprises a first part, a second part and an extension part arranged between the first part and the second part, wherein the two ends of the extension part are separately fixedly connected with the first part and the second part, connecting parts are arranged between the first part and/or the second part and the extension part, and the connecting parts are used for enhancing connection strength between the first part and/or the second part and the extension part. According to the shore crane, theextension part is arranged between the first part and the second part of the front girder so as to extend the length of the front girder, the first part or the second part is connected with the extension part through the connecting part to jointly form a stable triangular support structure, so that the connection strength between the two is enhanced, the structural strength of the whole front girder is improved, and the extension part can well meet the use safety requirement of the front girder. The invention further discloses an extension method for the front girder of the shore crane. The method is used for extending the shore bridge.
本发明公开了一种岸桥,包括前大梁,前大梁包括第一部分、第二部分以及设于第一部分和第二部分之间的延伸部,延伸部的两端分别与第一部分和第二部分固定连接,第一部分,和/或,第二部分和延伸部之间设有连接部,连接部用于增强第一部分,和/或,第二部分与延伸部之间的连接强度。本发明提供的一种岸桥通过在前大梁的第一部分和第二部分之间设置了延伸部使得前大梁的长度得以增长。第一部分或者第二部分通过连接部与延伸部连接,共同形成了稳定的三角形支撑结构,增强了两者之间的连接强度,提升了整个前大梁的结构强度,使得延伸部能够很好的满足前大梁的使用安全要求。本发明还公开了一种岸桥前大梁的延长方法,用于延长前述岸桥。
