The invention relates to a floating crane with a variable suspension arm. The floating crane with the variable suspension arm comprises a deck, a sliding track, a suspension arm sliding device and a floating crane, the top of the deck is connected with the bottom of a sliding rail, a suspension arm sliding device is arranged on the sliding rail in a sliding fit mode, and a floating crane is arranged between the deck and the suspension arm sliding device; the suspension arm sliding device comprises a sliding type suspension arm support, a rolling type oil cylinder hanging frame, a sliding oil cylinder, a plug pin shaft and a plug pin oil cylinder. The bolt oil cylinder is installed in the sliding type suspension arm support, the rolling type oil cylinder hanging frame is installed on the sliding rail, a plurality of pin holes are formed in the sliding rail, and a first working position, a second working position and a third working position are sequentially arranged on the sliding rail. According to the floating crane, a hoisted object on a shore platform and an offshore platform can be hoisted to the floating crane hull, so that the hoisted object is carried to be transferred, the operation flexibility is improved, meanwhile, goods can be transferred without the cooperation of two ships, and the cost is saved.

    一种吊臂可变位式浮式起重机,所述吊臂可变位式浮式起重机包括甲板、滑移轨道、吊臂滑移装置、浮式起重机;所述甲板的顶部与滑移轨道的底部连接,滑移轨道上滑动配合有吊臂滑移装置,甲板与吊臂滑移装置之间设置有浮式起重机;所述吊臂滑移装置包括滑移式吊臂支座、滚动式油缸挂架、滑移油缸、插销轴与插销油缸;所述插销油缸安装在滑移式吊臂支座内,滚动式油缸挂架安装在滑移轨道上,滑移轨道上开设有多个销孔,滑移轨道上依次设置有一工作位、二工作位、三工作位。本发明可将岸上、海上平台上的起吊物吊至浮吊船体上,从而携带起吊物进行转场,提高了运转的灵活性,同时采用此方案不需要两艘船的配合即可时间货物的运转,节约了成本。
