Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a rotatable telescopic bracket arm. Background Art

[0002] A corbel is a structural component used to support and stabilize mechanical equipment, usually made of materials such as steel or concrete. They are widely used in construction, industry, and other fields to provide additional support and protection. Generally speaking, a corbel is designed to connect with other parts of the equipment to form a stable structure. It can be used to increase the stability of the equipment and prevent the equipment from moving due to external forces. In some cases, corbels can also be used to spread the load, thereby reducing the pressure on the main structure. Corbels are often used on heavy equipment or machines, such as excavators, cranes, concrete mixers, etc. In these equipment, the corbel plays the role of supporting and protecting the machine parts and ensuring that the equipment can remain stable during work.

[0003] In order to make heavy-load suspension and manually operated workstations safer and more reliable, a rotatable telescopic support arm is usually used. The design of the existing rotatable telescopic support arm is relatively complex, and there are certain difficulties in the manufacturing and use process. This not only increases the production cost, but also may affect the service life of the equipment. In addition, due to its structural characteristics, the rotatable telescopic support arm occupies a large space, which may cause a waste of resources in many occasions, and the flexibility and applicability of the rotatable telescopic support arm during use are also limited to a certain extent. Due to its relatively fixed design structure, it may not be able to play its maximum role in some special environments. Utility Model Content
