The invention discloses an annular crane. The annular crane comprises an annular track and a crane body, and the annular track comprises an inner ring guide rail (1) and an outer ring guide rail (2) which are concentrically arranged. The crane body comprises a large vehicle and a small vehicle (34) which runs on a main beam (33) of the large vehicle. The large vehicle is provided with an inner ring wheel (31) capable of moving on the inner ring guide rail (1) and an outer ring wheel (32) capable of moving on the outer ring guide rail (2). According to the annular crane, the inner ring wheel of the large vehicle is mounted on the inner ring guide rail, and the outer ring wheel of the large vehicle is mounted on the outer ring guide rail, so that the span of the crane is smaller than the radius of the outer ring guide rail. On the basis that the diameter of the outer ring guide rail is the same as that of the single-ring annular track, the inner ring guide rail is added and is concentrically arranged with the outer ring guide rail to form the double-ring annular track so that the span of the crane can be reduced by more than 50%, the size requirement of the crane is further reduced, and the design and manufacturing difficulty of the crane is effectively reduced.

    本发明公开了一种环形吊车,包括:环形轨道,所述环形轨道包括同心布置的内环导轨(1)及外环导轨(2);吊车,所述吊车包括大车及位于所述大车的主梁(33)上运行的小车(34);所述大车具有能够在所述内环导轨(1)上移动的内环车轮(31)及能够在所述外环导轨(2)上移动的外环车轮(32)。本发明提供的环形吊车,由于大车的内环车轮安装在内环导轨上,大车的外环车轮安装在外环导轨上,因此,吊车的跨距小于外环导轨的半径。在外环导轨与单环的环形轨道直径相同的基础上,增加内环导轨并于外环导轨同心布置形成双环的环形轨道,能够使得吊车的跨距减少50%以上,进而缩小了吊车的尺寸需求,有效降低了吊车的设计和制造难度。
