Abstract

The invention discloses a cantilever crane, an overhead working truck and a cantilever crane manufacturing method, relates to the field of engineering machinery, and aims to improve the structure of the cantilever crane and improve the bearing capacity of the cantilever crane. The arm frame comprises at least two nested arm sections. And at least one arm section comprises a first cover plate and a second cover plate. The first cover plate is constructed to be integral and comprises a first side plate, a top plate and a second side plate which are arranged in sequence; the first side plate and the second side plate are oppositely arranged, and the free ends, away from the top plate, of the first side plate and the second side plate are both convex or concave. The second cover plate is constructed to be integral and comprises a third side plate, a bottom plate and a fourth side plate which are arranged in sequence; the third side plate and the fourth side plate are oppositely arranged, and the free ends, away from the bottom plate, of the third side plate and the fourth side plate are configured to be convex or concave. The free ends of the first side plate and the third side plate are fixedly connected, and the free ends of the second side plate and the fourth side plate are fixedly connected, so that the first cover plate and the second cover plate define a closed contour.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a boom, an aerial work vehicle and a method for manufacturing the boom. Background technique [0002] Aerial operating vehicles are widely used in construction, municipal maintenance, fire protection and other fields. Among them, the blue plate aerial work vehicle refers to the aerial work vehicle that can use the family car license. The blue brand aerial work vehicle has the advantages of unlimited traffic in the city and simple operation, but the quality and size of the vehicle are strictly limited by national standards, making it difficult to apply the structure and parameters of conventional engineering aerial work vehicles. In recent years, with the gradual development of high-altitude vehicle products to large rice, its lightweight requirements are also getting higher and higher. [0003] At present, the section of the box-type single-section telescopic boom equipped ...
