The modular crane comprises a bridge frame, a moving trolley, a lifting hook device and a lifting device, a cavity for the moving trolley to move is formed in the middle of the bridge frame, rails are installed on the two sides in the cavity respectively, the moving trolley is installed on the rails, and the lifting device is installed on the upper side of the bridge frame. A fixed pulley set is installed on the moving trolley, a guide wheel set is installed on the side face, located at one end of the track, in the cavity, and the hook device is located below the moving trolley. The problems that a traditional crane is large in structural space requirement, the limiting range caused by the limiting position of a lifting hook is large, the distance between trolley tracks is limited by the lifting height and the lifting weight, the actual working position of the lifting hook cannot meet the field working condition requirement, and safety and reliability are poor are solved.
一种固定式起升机构的模块化起重机及其运行方法,包括桥架、移动小车、吊钩装置以及起升装置,桥架中部具有移动小车移动的空腔,空腔内的两侧分别安装有轨道,移动小车安装在轨道上,起升装置安装在桥架的上侧,移动小车上安装有定滑轮组,空腔内位于轨道一端的侧面上安装有导向轮组,吊钩装置位于移动小车的下方。本发明解决了传统起重机结构空间需求大,吊钩极限位置造成的限制范围大,小车轨道间距受限于起升高度和起升重量的影响,吊钩实际工作位置无法满足现场工况要求以及安全可靠性差的问题。
