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.

La grúa de bandera móvil tiene una envergadura de suspensión mayor y es económica y duradera. Está equipado con una agencia de viajes incorporada, más segura y de menor tamaño, lo que resulta especialmente beneficioso para aumentar la carrera del anzuelo. Para la grúa de brazo móvil SEVENCRANE con equipo de elevación, todas las placas de acero obtenidas se colocan en la base del brazo. Los programas informáticos que se utilizan actualmente tienden a prestar atención únicamente a la distribución uniforme de las barras de acero curvadas longitudinalmente a lo largo del suelo de las vigas cajón. Aunque las barras de acero longitudinales son suficientes. Sin embargo, de acuerdo con las características del análisis de tensión de la situación real, debido a la concentración de tensión en la raíz del extremo del voladizo, la malla de fibras en las raíces de ambos extremos disminuye gradualmente.

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.
