Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a one-time molding unit for crane arm profiles. Background technique [0002] The boom of the truck crane is the most important part of the crane. The crane uses the pulley block at the top of the boom to support the hoisting wire rope to hang heavy objects, and uses the length and inclination of the boom to change the lifting height and working radius. Before manufacturing the boom of the crane, it is necessary to form the profile. The existing forming unit requires high-intensity manpower to participate in the use process, and the manufacturing efficiency and precision are relatively low. Contents of the invention [0003] The invention provides a one-time molding unit for crane arm profiles, which is simple in structure and easy to use. The whole processing process truly realizes automation, intelligence and continuity, and improves the efficiency and quality of production....
