The present invention relates to a crane boom assembly with easy replacement of a wire rope and, more specifically, to a boom assembly including multiple booms ranging from first to nth, provided in a telescopic structure to be extendable; a cylinder provided to connect the first boom and the second boom to lead the second boom to be moved into and out from the first boom; a wire rope for withdrawal extending the multiple booms by withdrawing the same when the cylinder is operated; and a wire rope for lead-in contracting the multiple booms by leading the same in when the cylinder is operated. The wire rope for lead-in has its one end fixed to the first boom on the outermost side, while having the other end fixed to the nth boom on the innermost side, which is moved into and out from the first boom, and the wire rope for lead-in between the first boom and the nth boom is wound on a sheave provided on the second boom to be rotatable. Therefore, the present invention is capable of reducing time and costs for assembly.

    본 발명은 와이어 로프의 교체가 용이한 크레인 붐조립체에 관한 것으로, 텔레스코픽 구조로 신축되게 구비되는 1단에서 n단까지의 다단 붐과, 1단 붐과 2단 붐을 연결하도록 구비되어 1단 붐에서 2단 붐을 출입시키는 실린더와, 실린더의 작동시 다단 붐을 인출시켜 신장시키는 인출용 와이어 로프와, 실린더의 작동시 다단 붐을 인입시켜 축소시키는 인입용 와이어 로프를 포함하는 붐조립체로서, 인입용 외어어 로프는 그 일단부가 최외측의 1단 붐에 고정되게 구비되는 한편 타단부는 1단 붐에서 출입되는 최내측의 n단 붐에 고정되게 구비되고, 1단 붐과 n단 붐 사이의 인입용 와이어 로프는 2단 붐에 회전가능하게 구비된 시브에 권취되어 구비되는 붐조립체를 제공한다.
