The aim of this task was to design a lifting device which is designed to a factor of safety of 1 to 2 electromechanically and 2 to 3 structurally meaning the device must fail if given a 1 or 1.5kg weight to lift. Initially, individual components were designed separately. Team members brainstormed and integrated ideas of the final design. Sketches were created and discussions were held through zoom meetings, regarding the proposed function of the components and the overall device. Following developments of these designs, some components were virtually constructed both individually and in combination with other components. After the creation of the final design, the crane was modified to improve the efficiency and overall functionality. Some components such as the design of the truss and the base structure were redesigned to help the final design be most efficient in terms of material use. As such, the performance of the device during formal assessment is expected to be successful and complete all the requirements of the project brief.

The design must also be structurally balanced and stable, so it does not tip when operating. Electrical energy must be its initial source and therefore, cannot use pre-stored electrical energy or pre-compressed springs. Furthermore, the design must achieve additional criterion and requirements to satisfy the client. Hence, this written design report will be outlining the entirety of the design concept. This will cover further analyses of the three main engineering disciplines; civil (structural), mechanical and electrical. This report will also include all calculations, diagrams, concepts, methodology that is used and implemented for the designed crane to function effectively whilst adhering to the design objectives.
