Description

Technical Field

[0001] The utility model relates to the technical field, and more particularly to a beam lifting machine support leg sling. Background Art

[0002] This beam hoist leg sling is a specialized lifting device used for installing, removing, and maintaining beam hoist legs. Beam hoists are essential equipment commonly used in large bridge construction, and the installation and maintenance of their legs are crucial to the safety and efficiency of the entire construction process. This sling incorporates advanced engineering mechanics principles and safety design concepts to improve the safety, precision, and efficiency of beam hoist leg operations.

[0003] In the existing technology, firstly, the applicability and flexibility of the slings of some devices are low, the installation is inaccurate, and the sling angle needs to be manually adjusted, which increases the difficulty and workload of operation. Secondly, some devices are difficult to clamp accurately, which may cause the legs to slip or be damaged. There is a lack of a stable clamping mechanism, and the sling may shake during the lifting process. Manual clamping and releasing of the legs will take more time, reducing overall work efficiency. Finally, the position adjustment of the hook assembly of some devices is more complicated, which limits the applicability of the sling. The hook assembly may not be stably fixed, and the maintenance and replacement of the hook assembly will become complicated. Utility Model Content
