Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of frame-type slings, in particular to a frame-type combined sling. Background Art
[0002] Compared to traditional cast-in-place construction, prefabricated buildings have gained increasing recognition, become increasingly popular, and are now being applied to various sectors of the construction industry. These advantages include reduced on-site workload, easier construction, improved on-site conditions, high machining precision, and easier quality assurance. However, due to various factors, a series of problems have arisen during the implementation of prefabricated projects, hindering their widespread adoption. This is particularly true with regard to hoisting construction, where traditional lifting points still offer significant room for improvement in stability, particularly after lifting.
[0003] In the existing technology, the frame-type sling cannot be adjusted or changed according to the size of the hoisted equipment, which will result in a small volume being equipped with a large-sized sling or a large volume being equipped with a small-sized sling, greatly reducing the scope of application. In addition, relying solely on ropes to lift the large equipment during the lifting process will lead to insufficient stability of the large equipment.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
