Abstract

Ergonomic activity significantly reliant with accidents at workplaces. Besides, ergonomic and safety are related with each other to keep society safe. Earlier study stated that 90% of 112 houses install Room Air-Conditioning in Malaysian home. Installing air-conditioning outdoor unit led into several problems which is un-ergonomic and less safety factor. Ductless Mini-Split Air-Conditioner demand in Malaysia from 2013 until 2015 was 2,407 thousand installation. 30 sets of questionnaires have been distributed to develop the House of Quality. Then, SolidWorks software has been used in designing portable outdoor unit lifter. This portable outdoor unit lifter could lift outdoor unit until 8feets. The used of hand-winch gear ratio was 3.4 in this product. In addition, the appropriate gear ratio was 5.33 for 2HP outdoor unit which weight around 40kg. Thus, this product also can handle up to 70kg of outdoor unit. Hence, this project developed to reduce energy and increase safety factor to workers.
