Design, fabrication and testing of hydraulic crane

Abstract

In this paper, design, fabrication and testing of hydraulic crane is intended to replace the local or traditional method of lifting heavy load with hand with emphasis being laid on performance, safety and reliability. Also, hydraulic crane is capable of carrying load up to 1000kg at a time was developed using locally available materials. The crane is comprised of six primary load-carrying members that are joined together in a particular fashion, actuator, oil tank, hose, pipe and a pump that is powered by a D.C. motor. The principle of operation, fabrication details and methods were critically analyzed, calculations were clearly laid out and material selection and costing were also discussed. The machine Factor of Safety (FOS) is 2 and in the performance evaluation, it indicated 81.2% efficiency.
