The movable jib crane has a larger suspension span and is economical and durable. It is equipped with a built-in travel agency, which is safer and smaller in size, which is especially beneficial to increasing the stroke of the hook. For SEVENCRANE movable jib crane with lifting equipment, all steel plates obtained are placed on the base of the jib. Computer programs currently in use tend to only pay attention to the uniform distribution of longitudinally curved steel bars across the floor of the box girders. Although the longitudinal steel bars are sufficient. However, according to the characteristics of the stress analysis of the actual situation, due to the stress concentration at the root of the cantilever end, the fiber mesh at the roots at both ends gradually decreases.

Features of jib crane: First of all, the cantilever crane has a lightweight structure, is easy to operate, is flexible, adaptable, and affordable, which greatly saves input costs, while reducing the labor intensity of workers and improving work efficiency. The jib crane solves the weakness of fixed cranes that are prone to site restrictions and is an ideal equipment for repair and installation.

Cantilever cranes include curved arm cantilever cranes, fixed column cantilever cranes, mobile cantilever cranes, and double-arm cantilever cranes. Although they have different names, they also have common characteristics. For example, it occupies a small area, has high work efficiency, and has relatively high reliability when in use. It is very suitable for short-distance lifting and transportation, has a high frequency of use, and can perform relatively intensive lifting work.
