Description

Technical Field

[0001] The invention relates to an automated logistics system on an automobile production line, in particular to a large-stroke side ejector with a simple and compact structure. Background Art

[0002] A side jacking machine is provided on an automated automobile production line. The side jacking machine is used to lift the welded body frame to achieve the purpose of separating it from the running automated production line.
