Description

[0002] At present, the current material transportation process such as mechanical industry often faces the situation of rush transportation, and the lifting mechanism often misidentifies and transships incorrectly. Moreover, the lifting mechanism needs to move and transport the objects on the transportation line, so that the normal materials behind the area cannot continue to be transported by passing through the mechanism, and a large amount of manual intervention is required to distinguish. Since the transportation line body itself is relatively long, it not only takes time and is inefficient, but also affects the effect of transshipment. Moreover, the protection measures of some transportation lines themselves for the mechanism are not enough, so that the materials fall and damage the transportation line body during the lifting process.
