Abstract: A crane assembly includes a main body, a boom, a hoist, a sheave, a hook assembly including a hook, a cable, and a projection. The boom extends from the main body and includes a tubular main section and a tubular extension section telescopically nested within the tubular main section. The boom has a first end pivotally coupled to the main body. The hoist is coupled to at least one of the first end of the boom and the main body. The sheave is disposed at an opposing second end of the boom opposite to the main body. The cable extends from the hoist, along the length of the boom, over the sheave, and downward to the hook assembly. The projection extends outward from the boom and toward the main body.

Abstract: 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.

Abstract: 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.
