【 摘 要 】

Patient lifting equipment can help the lifting of patient movement completely. It can help reduce the risk of disease that can be caused by lifting the patient and reduce the impact on the patient caused by lifting the patient in the wrong way. In addition, it can help to reduce the working time and reduces the number of personnel in moving patients. Including it can be to prevent the occupational disease on the service providers. This study aims to analyze the stress distribution and displacement to design of patient lifting equipment. The three weight conditions of 60 kg, 80 kg, and 120 kg are considered for studying about stress distribution and displacement at various points. In this test, ASTM A36 steel is used as a strength material tester. The results found that the maximum stress distribution and displacement is in the sling bar of the equipment. The obtained values will provide a basis for the guideline to design of patient lifting equipment to lift patients to suit in each situation such case from a private car go to bed or and wheelchair and from bed or and wheelchair go to a private car.
