Disclosed are a mobile crane device and an assembling method thereof. The mobile crane device of the present invention comprises: a cylinder portion supported on a base portion; a mast portion connected to the cylinder portion so as to rise as the cylinder portion is elongated; a crane portion mounted on the mast portion and winding or unwinding a lifting cable; a plurality of divided pipe portions connected to the lifting cable, assembled to surround the cylinder portion and the mast portion by driving of the crane portion, and forming a divided module stacked in a plurality of layers; a plurality of support bars rotatably coupled to the divided pipe portion to protrude toward the inside of the divided pipe portion, and supporting the cylinder portion so that the cylinder portion moves to an upper side of the divided module when the cylinder portion is driven; and a lifting guide portion installed on the mast portion to move in a longitudinal direction of the mast portion, and detachably coupled to the plurality of support bars to support the mast portion when the mast portion moves.

    이동식 크레인장치 및 그 조립방법에 대한 발명이 개시된다. 본 발명의 이동식 크레인장치는: 베이스부에 지지되는 실린더부; 실린더부가 신장됨에 따라 상승되도록 실린더부에 연결되는 마스트부; 마스트부에 탑재되고, 인양 케이블을 권취하거나 풀어주는 크레인부; 인양 케이블에 연결되고, 크레인부의 구동에 의해 실린더부와 마스트부를 둘러싸도록 조립되고, 복수 층으로 적층되는 분할모듈을 형성하는 복수의 분할관부; 분할관부의 내측을 향하여 돌출되도록 분할관부에 회전 가능하게 결합되고, 실린더부의 구동시 실린더부가 분할모듈의 상측으로 이동되도록 실린더부를 지지하는 복수의 서포트바; 및 마스트부의 길이방향을 따라 이동되도록 마스트부에 설치되고, 마스트부의 이동시 상기 마스트부를 지지하도록 복수의 서포트바에 착탈 가능하게 결합되는 리프팅 가이드부를 포함하는 것을 특징으로 한다.
