The invention discloses a mast device and a circular track crane, and relates to the field of engineering machinery. The mast device and the circular track crane are used for meeting the requirements for overall stability of an amplitude-change surface and a revolution surface of a mast and meeting the requirements for combined transformation of a cart and a trolley and container type transportation in a limited space. The mast device comprises at least two arm frame assemblies, wherein each arm frame assembly comprises a bottom section, a middle section and a top section which are sequentially arranged; each middle section comprises at least two arm frames which are arranged in parallel, and the two arm frames of each middle section are fixedly connected through the corresponding bottom section and the corresponding top section. According to the technical scheme, the mast device is good in overall stability, good in interchangeability and good in universality; the requirements of different types of circular track cranes for the mast device can be met; and in addition, the mast device adopts an arm frame structure, so that the requirements for overall stability of the amplitude-change surface and the revolution surface of the mast can be met in the limited space, the requirements of different types of circular track cranes are met, and the requirements for container type transportation are met.

    本发明公开了一种桅杆装置以及环轨起重机,涉及工程机械领域,用以在有限空间下既能满足桅杆变幅面及回转面整体稳定性要求,又满足大小车组合变换、集装箱式运输要求。桅杆装置包括至少两个臂架组件,每个臂架组件包括依次布置的底节、中间节以及顶节;中间节包括至少两根平行布置的臂架,中间节的两个臂架通过底节和顶节固定连接。上述技术方案提供的桅杆装置,整体稳定性好、互换性好、通用性好;可以实现不同型号的环轨起重机对桅杆装置的要求。并且,桅杆装置采用臂架结构,在有限空间下既能满足桅杆变幅面及回转面整体稳定性要求,又满足了不同型号的环轨起重机的要求,又满足了集装箱式运输的要求。
