In a conventional hook block storage device, a dead space is generated in a lower portion of a hook block at a storage position, and when driving on a rough road, deflection of the hook block is generated. A hook block central line (42) connecting a hook sheave shaft (7) and a trunnion shaft (15) of a hook block (10) is approximately parallel with a flexible boom central line (43) at a storage position. Moreover, at the storage position, an offset amount of a top sheave shaft (6) of a boom head (2) is smaller than that of a hook sheave shaft (7) of the hook block (10).

    [과제] 종래의 훅 블록 격납 장치에서는, 격납 위치에서의 훅 블록 하(下)에 데드 스페이스가 발생하고, 험로 주행시에는 훅 블록의 처짐이 발생한다. [해결 수단] 격납 위치에서의 훅 블록(10)의 훅 쉬브축(7)과 트러니언축(15)을 연결하는 훅 블록 중심선(42)이 신축 붐 중심선(43)과 대략 평행하게 되고, 또한 격납 위치에서의 붐 헤드(2)의 톱 쉬브축(6)의 오프셋량이 훅 블록(10)의 훅 쉬브축(7)의 오프셋량보다도 작게 되도록 했다.
