Parallel orbital transfer device for mobile crane

The utility model discloses a parallel orbital transfer device for a mobile crane, which comprises at least two pairs of working double rails which are arranged in parallel; the transfer double track is perpendicular to the working double track and is arranged at one end of the working double track; and the transfer trolley is used for bearing the mobile crane and moving the mobile crane from the end parts of one pair of working double rails to the end parts of the other pair of working double rails. According to the technical scheme, the parallel track transfer device provided by the utility model has the advantages that only one mobile crane with a normal span can be used, large-range hoisting and hoisting can be realized through position transformation between the parallel tracks, and the cost can be effectively reduced. 本实用新型公开了提供一种用于移动式起重机的平行变轨装置，包括工作双轨，至少两对所述工作双轨平行设置；转移双轨，垂直于所述工作双轨，并且设置于所述工作双轨的一端；转移车，用于承载所述移动式起重机，并将所述移动式起重机从一对工作双轨的端部移动至另一对工作双轨的端部。通过上述技术方案，本公开提供的平行变轨装置可只使用一台正常跨径的移动式起重机，通过平行轨道间的位置变换，实现大范围
