摘要： A boom for a crane assembly includes first and second sections. The second section is configured to be at least partially nested within the first section of the boom, and is further configured to slide relative to the first section of the boom. Each of the first and second sections of the boom have a tubular cross-section. Furthermore, the first and second sections of the boom each include first and second pieces. The first piece has two edges extending lengthwise along the respective section, and the second piece has two edges extending lengthwise along the respective section. The first and second pieces are arranged such that the two edges of the first piece overlap the two edges of the second piece, and the first and second pieces are welded together along an exterior end of the overlapping edges.

摘要： A crane assembly includes a main body, a boom extending from the main body, a cable, and a hook coupled to an end of the boom opposite to the main body by the cable, where the crane assembly is configured for lifting items via the hook. The crane assembly further includes a projection extending outward from the boom and curving toward the main body. The projection is configured to receive the hook over an end of the projection such that tension in the cable maintains the hook in place on the projection. Gravity is sufficient to release the hook from the projection when the boom is raised and the tension in the cable is released.
摘要翻译：起重机组件包括主体，从主体延伸的起重臂，电缆以及通过电缆联接到与主体相对的动臂的端部的钩，其中起重机组件构造成用于通过钩提升物品。起重机组件还包括从起重臂向外延伸并朝向主体弯曲的突起。突起构造成在突出部的一端接收钩，使得电缆中的张力将钩保持在投影上的适当位置。当吊杆升高并且电缆中的张力被释放时，重力足以从突起释放钩。
