Description

Technical Field

[0001] The invention relates to the field of container bag sling production, in particular to a container bag sling cutting and marking machine. Background Art

[0002] After the container bag is loaded, two or four straps are usually sewn on the bag body for the convenience of lifting. The container bag strap is the load-bearing component connecting the container bag body and the lifting equipment. It is generally made of high-strength fiber materials such as polyester, nylon, etc., with high strength and flexibility; during the lifting and transportation process, the container bag strap can evenly distribute the weight of the cargo in the container bag and transfer it to the lifting equipment, ensuring that the container bag can safely lift and carry tons or even tens of tons of cargo. At the same time, it provides a connection point for the lifting equipment, making it convenient for forklifts, cranes and other equipment to connect to the container bag strap through hooks, slings, etc., to realize the lifting, handling and loading and unloading operations of the container bag, thereby improving the efficiency of logistics transportation; during the lifting process, the container bag strap can ensure the balance and stability of the container bag and the cargo it carries through the straps reasonably distributed around the container bag, preventing the cargo from tilting, shaking or even falling during the lifting process, and ensuring safe operation.
