Design and Analysis of Lifting Carriage of 4T Overhead Stacker Crane

Abstract

The Overhead Stacker Crane is a hybrid device that combines the features and constructions of "Industrial Forklifts" and "Electric Overhead Cranes." Stacker cranes are equipment with varied levels of automation that are used to store materials. They travel along the aisles of the operating areas, where they enter, position, or extract the material. This type of crane is widely used in assembly shops, production stores, warehouses, etc. Each application needs customizing. The lifting carriage of different overhead stacker crane design is studied in this study. The new design has two advantages: the lifting carriage is bracketed to the mast of the overhead stacker, and the new lifting mechanism is more compact. The most common structure configurations are single-mast and twin-mast constructions. Single-mast structures are used for investigation in our research. A live example has been chosen, and several design engineering stages have been implemented, with the goal of achieving compliance with safety-related standards as well as possible enhancements for future consideration. All the concerned parts have been 3D modelled, analyzed using classical means as well as advanced means of FEA. The goal of using design engineering concepts is to provide a verified design with documentation that can be manufactured with or without indicated improvements. Static analysis of identified parts is performed using both hand calculation and the FEA approach.
