Cantilever cranes are a common type of crane. With its unique structure and flexible operating characteristics, it plays an important role in many fields. Understanding the common types of cantilever cranes will help to make reasonable selections and applications according to actual needs.
1. Fixed-column cantilever crane
The fixed-column cantilever crane is a relatively basic type. It is mainly composed of columns, cantilevers, slewing mechanisms and other parts. The columns are usually fixed on the ground foundation to provide stable support for the entire crane. The cantilever is installed on the top of the column and can rotate in a circle around the column. The slewing mechanism ensures that the cantilever can rotate smoothly to lift goods in different positions.
This type of cantilever crane has a relatively simple structure and a low cost. It is suitable for some places with small lifting weights and relatively fixed working ranges, such as workshops in small factories, for lifting small parts or tools. Its working radius is generally determined according to design requirements, usually between several meters and more than ten meters.
2. Wall column cantilever crane
Wall column cantilever crane is different from fixed column type. Its column is installed on the wall or building column. This design saves ground space and is particularly suitable for environments with narrow sites. It also has a cantilever and a slewing mechanism, which can realize the lifting of goods within a certain range.
The lifting capacity and working radius of the wall column cantilever crane vary depending on the specific design and installation location. Installing a wall column cantilever crane near the wall in some warehouses and workshops can make full use of the space and facilitate the loading, unloading and handling of goods near the wall. It can play a greater role in a limited space and improve space utilization and work efficiency.
3. Articulated arm cantilever crane
The cantilever shape of the articulated arm cantilever crane is curved, which is a significant feature that distinguishes it from other types. This special structural design enables the cantilever to cross some obstacles when lifting goods, or reach some places that are difficult to reach with ordinary straight cantilever.
Articulated arm cantilever cranes are usually equipped with more complex control systems to ensure that the articulated arm can move according to the predetermined trajectory. It is suitable for some occasions with special requirements for the lifting position. For example, in some workshops with dense equipment and complex spatial layout, the goods to be lifted may be blocked by other equipment. At this time, the curved arm cantilever crane can flexibly avoid obstacles with its unique curved arm structure and complete the lifting task of the goods.
4. Electric hoist cantilever crane
Electric hoist cantilever crane is a type that combines electric hoist with cantilever crane. As a lifting mechanism, the electric hoist has the advantages of fast lifting speed and easy operation. It is installed on the cantilever and realizes the lifting and lowering of goods through electric drive.
The working efficiency of the electric hoist cantilever crane is high and it is suitable for occasions with frequent lifting operations. In some automated production lines, the electric hoist cantilever crane can work closely with other production equipment to realize the rapid lifting and precise positioning of goods, and improve the continuity and efficiency of the entire production process. At the same time, since the lifting capacity of the electric hoist can be selected according to demand, this type of cantilever crane can adapt to the requirements of different lifting weights.
5. Manual jib crane
A manual jib crane is a relatively simple type of jib crane, and its operation mainly relies on manpower. It is generally simple in structure and low in cost. Manual jib cranes are usually equipped with manual lifting devices, such as hand chain hoists, and operators manually pull chains or ropes to lift and lower goods.
Manual jib cranes are suitable for places with small lifting weights and low working frequency. In some small workshops or maintenance workshops, manual jib cranes can easily lift and install some small equipment or parts to meet basic work needs. Although its work efficiency is relatively low, it is still widely used in some specific occasions due to its low cost and simple operation.
