Description

Technical Field

[0001] The utility model relates to the technical field of European-style hoist limiting installation structures, in particular to a European-style hoist limiting installation structure. Background Art

[0002] European-style bridge cranes are characterized by their light weight, compact structure, and low energy consumption. A trolley and lifting mechanism are mounted on the bridge. The trolley can move forward and backward, while the carriage operates, enabling the three-dimensional handling of materials. European-style cranes utilize a unique design concept, resulting in small size, light weight, and low wheel pressure. Compared to traditional cranes, the maximum distance from the hook to the ground (floor) is minimized, resulting in the lowest headroom. Keli cranes can operate closer to the front and achieve higher lifting heights.

[0003] A European-style gourd limiting installation structure disclosed in the Chinese utility model patent application disclosure CN 215402787 U, although it effectively improves work efficiency, but when installing the gourd body, the gourd body can only be hung on the threaded sleeve by a hook, which easily causes the gourd body to shake and there is a probability of falling off, resulting in the gourd body being unstable. Therefore, there is a problem that the gourd body is not stable enough after installation. During installation, the limiting device of the equipment uses a spring bayonet to adjust the height of the limiting rack, and the limiting rack limits the movable rack through a circular gear. The operation steps are relatively cumbersome, resulting in the operation of the limiting device being not convenient enough. Therefore, there is a problem that the operation of the limiting device is not convenient enough. In summary, this utility model has the problems that the gourd body is not stable enough after installation and the operation of the limiting device is not convenient enough. Utility Model Content
