移动式旋臂起重机悬挂跨度较大，经济耐用。配备内置行程机构，更安全，体积更小，特别有利于增加吊钩行程。对于带有起重设备的 SEVENCRANE 移动式旋臂起重机，所有获得的钢板都放置在旋臂底座上。目前使用的计算机程序往往只关注箱梁地板上纵向弯曲钢筋的均匀分布。虽然纵向钢筋已经足够了。但根据实际情况的应力分析特点，由于应力集中在悬臂端根部，导致两端根部纤维网格逐渐减小。

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.
