Abstract

A stainless steel lifter comprises a lifting guide frame, a fixing guide frame, a lifting roll passage, a front positioning mechanism, a rear positioning mechanism, a synchronous mechanism, a rear positioning upper stopper and a front positioning lower stopper. The stainless steel lifter lifts stainless steel coils by extending diploid strokes through a hydraulic cylinder of the lifting guide frame. By utilizing a diploid stroke principle, the total height of the stainless steel lifter is 2/3 of a conventional design, thereby greatly reducing the depth of an equipment foundation and lighteningequipment weight. Compared with the lifting scheme of a climbing chain-type conveyor, the stainless steel lifter saves a section of a long climbing chain-type conveyor arranged for lifting, and savesthe equipment foundation and investment of factory buildings.
