Abstract

The difficulties and time consuming of manual labour process for digging an opening grave has motivated this project. Although significant invention of commercialized earth digging machines i.e. excavator, tractor, loader, etc. has been developed, the existing invented machines were not suitable to be used at the challenging graveyard site as well as its strict requirements. Few of the challenges are tight working areas in terms of moving and placing the machine, to avoid collapsing of adjacent graves and/or compaction of ones nearby and lastly to keep the environment noise as minimum as possible. Based on the aforementioned challenges and difficulties, the development of efficient square hole digging machine are necessitate. Apart on solving the discrepancies faced by the current machines, the development of the machine required extensive consideration such as soil type, power source, structural analysis, fabrication method as well as costing which will be the main contents of this project. To realize the development of the machine, engineering design tools were employed namely Design for Manufacture and Assembly (DFMA), Pugh’s Selection Method and Structural Finite Element Analysis. Based on the constraints and requirements, three preliminary propose design are evaluate and one of the best solution will be select for the prototype development. Lastly the effectiveness of the prototype will be validate and evaluate. Based on the developed square hole digging machine prototype, it was found that the machine capable of digging square hole with ease, reasonable operating time and ease of transportation to the tight working area
