Fixed-column jib crane is a light lifting equipment. Its main features are sensitive response, simple and convenient operation, and wide range of use. Such as production workshops, installation lines, production lines, garages, docks, etc. For example, the maintenance of some products may also use fixed-column cantilever cranes. This type of crane is more suitable for low-altitude operations, and the rotation angle is 360° or less than 180°. Of course, in terms of angle, ordinary users can choose according to their own needs, or they can be customized. Basically, this type of crane meets the requirements of JB/T 8906-1999, and the working intensity is medium-sized.

Wall-mounted cranes support workshop processes, and for adjacent workshops our wall-mounted jib cranes are the ideal workstation cranes. They can transport materials to various workstations and can also be used for positioning operations at assembly stations. This type of crane operates under an overhead crane on crane rails that run up and down the workshop walls.

The mobile girder rail gantry crane consists of the main beam, rigid and flexible door legs, operating trolley, lifting mechanism, cart operating mechanism, electrical system, operating cab, etc. According to the yard operation process, the cantilever can be extended in the direction of the single door leg or the double door leg to become a single cantilever or double cantilever model, and if it is not extended, it will be a non-cantilever model. According to the location, container storage and transportation process, and loading and unloading vehicles (container trucks or railway vehicles), confirm the selection of different structural methods without cantilever, single cantilever, and double cantilever.

Gantry cranes are widely used in various industries of the national economy such as metallurgy, electric power, ports, logistics, machinery manufacturing and marine engineering. They are important process equipment for industrial production and are related to the safety of people's lives and the safety of national economic operations. and social stability are important components of public security in all countries. The development momentum of my country's hoisting machinery industry is strong. As of the end of 2017, the number of hoisting machinery in my country reached 2.2375 million units. According to the "Notice of the State Administration for Market Regulation on the Safety Status of National Special Equipment in 2017", the accident rate and fatality rate of cranes in my country rank first among the eight categories of special equipment. Therefore, there is an urgent need for an effective means to ensure the safety of in-service cranes. Safe and reliable operation of machinery.

The rolling gantry crane is typically used for lifting and moving heavy loads in areas where a permanent overhead crane system may not be feasible or practical. It offers a flexible solution for material handling tasks that require frequent relocation or where a fixed crane installation is not economically viable. One of the primary advantages of a rolling gantry crane is its mobility. The wheels attached to the vertical legs or columns enable easy movement and positioning of the crane. The wheels are often equipped with brakes or locking mechanisms to ensure stability and safety during operation. This mobility allows the crane to be used in various areas within a facility, optimizing workflow and reducing the need for multiple fixed cranes.

The jib crane is a light crane suitable for low work intensity. It consists of three parts: a column, a swing arm and a driving device, and an electric hoist. The bottom of the column is fixed on the concrete or movable chassis through anchor bolts. The cantilever is a hollow steel structure with the characteristics of light weight, large span and fast running speed under hoisting load.
