Description

Technical Field

[0001] The utility model relates to the technical field of double-beam cranes with a telescopic frame structure, and more specifically, to a double-beam crane with a telescopic frame structure. Background Art

[0002] In the current technological environment, double-beam cranes with telescopic frame structures are widely used in the industrial field, mainly for material handling and loading and unloading. Due to the design of the telescopic structure, this type of crane can adjust the span according to the operation requirements to adapt to different occasions. However, a significant problem is that in actual use, the lifting arm can usually only rely on a single arm for support. Although this design simplifies the mechanical structure, the single-arm support is prone to stability and safety issues when used for a long time or under heavy load.

[0003] First, the single-arm support method will produce a large pressure concentration when bearing heavy objects, which not only increases the wear rate of the lifting arm itself, but may also cause structural deformation or damage, especially in continuous operation or overload conditions. In addition, the single-arm support will also affect the operational stability of the crane, because the heavy objects are prone to swing during the movement, further increasing the operational risks. In extreme cases, this swing may cause the cargo to fall off, resulting in material losses or injuries to the operators.

[0004] Secondly, due to the stability problem of the single arm support, the use effect of the crane is significantly affected. When performing precise positioning or handling sensitive materials, the swing of the single arm may cause operational difficulties and reduce work efficiency and accuracy. In the long run, this will not only affect production efficiency, but may also increase the cost of safety management and equipment maintenance for enterprises. Utility Model Content
