The invention relates to a crane housing (100) for a leg-winding crane (1) to be mounted on a pivotal bearing. The crane housing comprises an annular base assembly (105), two support assemblies (108a, 108b) and a front assembly (106), each assembly having a bulkhead (101). The support assemblies are connected to the annular base assembly (105) on respective sides of the forward section of the annular base assembly. The front assembly is connected to the front section of the annular base assembly between the two support assemblies to interconnect them. The two support assemblies and the front assembly together form a front torsion box (400) that provides torsional stiffness. In addition, the load of the boom when applied on the support assembly subjects the base assembly to torsions distributed across the front section of the base assembly via the torsion box.
待安装到回转轴承上的用于绕腿起重机(1)的起重机外壳(100)。起重机外壳包括环形基座组件(105)、两个支撑组件(108a,108b)和前部组件(106),每个组件具有隔板(101)。支撑组件在环形基座组件的前部区段的相应侧面连接到环形基座组件(105)。前部组件连接到环形基座组件的前部区段,位于两个支撑组件之间,以使它们相互连接。两个支撑组件和前部组件一起形成提供扭转刚度的前部扭转箱(400)。此外,施加在支撑组件上时的吊臂的负荷经由扭转箱而使基座组件经受分布在基座组件的前部区段上的扭转。
