The jib of portable mobile jib crane is usually made of high-strength high-quality steel, which has good strength and durability and can withstand heavy weight and frequent use.

The jib crane on wheels is a new generation of light lifting equipment made to adapt to modern production. It is equipped with a highly reliable electric chain hoist and is especially suitable for short-distance, frequently used, intensive lifting operations. It is efficient, energy-saving, trouble-free, and occupies space. It has small floor area and is easy to operate and maintain. The SEVENCRANE jib crane on wheels is more flexible and adaptable. It is an essential independent emergency hoisting equipment for efficient automatic production lines. It can ensure the smooth flow of the production line.

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.

The working intensity of the SEVENCRANE mobile jib crane with lifting equipment is light. The main structure of this type of jib crane is composed of a column, a slewing arm rotation drive device and an electric hoist. The lower end of the column is installed on a movable pedestal foundation, and a cycloidal pinwheel reduction device drives the cantilever rotation. The electric hoist moves left and right in a straight line on the cantilevered I-beam and lifts heavy objects. The crane's cantilever is a hollow steel structure with light weight, large span, large lifting capacity, economy and durability.
