Description

Technical Field

[0001] The present application relates to the technical field of folding arm spreaders, and in particular to a folding arm spreader. Background Art

[0002] A folding arm crane is a type of lifting machinery. It is a machine that performs cyclic and intermittent motion. A working cycle includes: the picking device lifts the object from the picking location, then moves horizontally to the designated location to lower the object, and then moves in the opposite direction to return the picking device to its original position for the next cycle. Usually, lifting machinery is composed of a lifting mechanism, a running mechanism, a luffing mechanism and a slewing mechanism, plus a metal mechanism, a power unit, an operating control and necessary auxiliary devices. During the production process of automobiles, folding arm cranes are needed to transport automobile parts.

[0003] For example, a Chinese patent (CN204727444U) discloses a sling for hanging a front bumper bar, comprising: a sling body; an adjusting hanging plate, the adjusting hanging plate is arranged at the upper end of the sling body, a plurality of shackles are arranged on the adjusting hanging plate and each of the shackles is adjustable relative to the adjusting hanging plate; a lifting ring, the lifting ring is connected to the shackle; a clamping assembly, the clamping assembly is fixed to the lower end of the sling body and is suitable for clamping the front bumper bar. According to the sling of the utility model, by adopting the clamping assembly and the displacement of the shackles on the adjusting hanging plate, front bumpers of different sizes can be hung and the lifting process is stable, which effectively reduces the labor intensity of workers and improves production efficiency.

[0004] The above scheme also has the following technical defects. The length of the upper crossbeam of the above scheme is relatively short. Therefore, in actual use, it can only be used in conjunction with a crane, and it is difficult to use in locations with a small crane space range. At the same time, it is too wasteful to use a crane to transport lightweight parts. At the same time, the upper crossbeam of the above scheme cannot be folded and extended, and other equipment needs to be used to transport the sling and parts. The scope of application is very limited. Based on this, a folding arm sling is proposed. Utility Model Content
