The invention discloses a girder assembly and door frame general assembly process of a container crane, which comprises the following steps: before hoisting, selecting and matching front and rear girder assemblies and a gantry crane hoisting device on a shoreside, and carrying out counterweight measurement by using a steel wire rope; and after the hoisting component is 100mm away from the jig frame, hovering and stabilizing, checking the hoisting device, holding and locking the pitching brake, and keeping the two hook heads of the portal crane synchronous in the hoisting process. According to the girder assembly and door frame general assembly process of the container crane, portal crane double-hook lifting is adopted, the traditional single-floating-crane single-hook lifting mode is changed, the limited water operation environment is expanded to land lifting, the influence of tide water and surges is avoided, lifting is more stable, and the service life of the container crane is prolonged. And the final assembly efficiency of the front and rear girder assemblies and the door frame of the quay crane is greatly improved.

    本发明公开了一种集装箱起重机的大梁组件与门框总装工艺,该集装箱起重机的大梁组件与门框总装工艺包括以下步骤:吊装前,做好岸边前后大梁组件与门机吊装装置的选配工作,使用钢丝绳进行配重测量;起吊构件离开胎架100mm后,悬停进行稳定,做好吊装装置的检查工作,将俯仰制动器抱紧锁死,在起升过程中门机两钩头保持同步。该集装箱起重机的大梁组件与门框总装工艺采用门机双钩抬吊,改变了传统的单一浮吊单钩吊装方式,也将局限的水上作业环境拓展到陆上吊装上面来,不受潮水及浪涌影响,吊装更平稳,也大大提高了岸桥前后大梁组件与门框的总装效率。
