Electro-mechanical lift system for stacking and off-loading of files

In an office environment like the University system, there is always the need to pick, stack and off-load office files on regular basis. Most times, these files are numerous and are stacked at a height, which is cumbersome to perform such work on routine basis. This research work was conceived out of this need to design a machine that can help in the overall performance of such activities. This machine was designed for stacking and offload files with allowable maximum load of 3kg.The machine consists of an AC motor, generating rotatory motion which gets converted to translational motion by the application of a pulley system mechanism installed in a vertical frame up a height of 2.5m which aids the linear movement (up and down) of the cantilever, as it carries the files to the desired height. The production and selection of materials for this research was carried out according to the design analysis and computations done with reference to engineering standards. It was produced and tested and was able to stack and off-load offices files within the design limit.
