[Detailed Description of the Invention] The present invention can be used to feed various articles to a lifter that raises and lowers automobiles that have been assembled or are in the process of being assembled in an automobile assembly factory to be transferred to a shipping conveyance line or another assembly line. Regarding the equipment for supplying the goods, specifically, an article conveying device that conveys the lifter side end of the article to be loaded onto the lifter to a state where it is placed on the lifter, and
In order to place the entire article to be loaded on the lifter,
The present invention relates to equipment for supplying articles to a lifter, each of which is provided with a device for locking and transferring the end portion of the article on the lifter side to the rear side of the lifter.

In such equipment, the locking transfer device has conventionally been attached to the lifter side, but in this case, the locking and transferring device must also be moved up and down when the lifter is raised and lowered, making it difficult to raise and lower the lifter. Due to the disadvantage of requiring driving force and the fact that the structure for supplying energy such as electric power to the driving part such as the electric motor in the locking conveyance device must be configured to be complicated to allow the lifter to move up and down. There was a disadvantage that the equipment was expensive and complicated, and there was room for improvement.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide an article for a lifter that can reduce the lifter lifting force and simplify the equipment through simple improvements. The point is to provide supply facilities.
