Description

White pig loading and unloading arm Technical Field The utility model relates to the technical field of loading and unloading of white pigs, and particularly discloses a loading and unloading arm of a white pig. Background In the field of meat processing and cold chain transportation, white pigs are used as important fresh products, and are usually lifted and transported efficiently and stably by means of equipment such as loading and unloading arms and the like, and are rapidly transferred into a cold chain car or a refrigerator car. This operation can significantly reduce the labor intensity of manual handling. Chinese patent No. CN209338007U discloses a handling arm for a white pig or a white cow, where the handling arm for a white pig or a white cow can stably and easily lift a white strip by using a fork, and hang the white strip on a cold chain car or a refrigerated car after rotation and lifting.
