Underhung cranes are light and small cranes that run on rails. They can be installed directly on the roof structure of the existing factory building without the need for corbels. Therefore, they can save space, reduce costs, and use the entire factory space for production. It has the characteristics of compact structure, good rigidity, sensitive operation, low noise, safety and reliability.

The necessary components in the lifting mechanism of underhung cranes include the following parts: Wire rope or chain: used to connect lifting objects to the crane and assume the role of lifting and suspending the lifting objects; chains are generally used for heavier lifting objects, while wire ropes are suitable for larger tonnages.

Our underhung cranes offer maximum stiffness and minimum dead weight. This keeps loads on the crane runway to a minimum and allows for an economical and energy-efficient design to be chosen for the building. This approach provides you with an economical and energy-efficient solution. They also include loading and unloading speed lifting devices with high energy rates and offer advantages over conventional cranes, resulting in excellent ride qualities, in order to increase overall efficiency.

Underhung cranes are lifting equipment that are placed horizontally over workshops, warehouses and stockyards for lifting materials. Because the two ends of the bridge's underhung cranes are located on tall cement columns or metal supports, and are shaped like a bridge, they are commonly known as "overhung cranes" and "driving cranes." It is a kind of lifting machinery with wide range of use and large quantity.

After understanding the basic parameters of underhung cranes, we must also understand the metal structure frame structure of the bridge crane in detail. Let’s share it with you. The metal structure of underhung cranes is the skeleton of the crane, on which all mechanical and electrical equipment are distributed. It is the load-bearing structure of the crane and makes the crane form a whole mechanical equipment.

As a workshop crane, the cantilever jib crane is the ideal workstation crane for side-by-side workstations. They are responsible for transporting materials to various workstations and completing positioning tasks at the assembly station. They move up and down along the workshop wall on slides below the level of the overhead crane. SEVENCRANE cantilever jib cranes are the ideal workstation cranes for adjacent workshops. 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.
