스키드로더 작업자의 안전성과 작업효율 향상을 위한 디자인 제안연구 : 스키드로더 디자인 사용성평가를 중심으로

The incidence of industrial accidents is also increasing due to various construction facilities used in the construction industry, which continues to grow due to industrial advancement. In order to prevent workers from being exposed to various accident risks, this study proposes a Skid Steer Loader design that meets the requirements for safe operation through proper specifications from the perspective of workers. The purpose of this study is to propose a Skid Steer loader design that secures safety and work efficiency from the operator's point of view, evaluate the usability of the proposed Skid Steer loader design, identify problems in usability, and propose directions for improvement. Research methods are described in the following order. Firstly, the background and purpose of the research are described. Through the literature investigation, this paper expounds the status quo of construction industry and the safety measures of construction equipment. Secondly, it expounds the theoretical background. This paper describes the contents of Skid Steer Loader design and development, usability evaluation, and visual point evaluation methods. Thirdly, the experimental process is described. Evaluation elements were developed for usability evaluation, and experiments conducted through the developed evaluation items were described. Fourth, the experimental results and conclusions are described. The experimental results grasp the problems of usability, put forward the direction of improvement, and put forward the limitations of the research. The limitation of the research lies in: First, it is difficult to select the evaluation factors due to the lack of similar research papers in the process of selecting the evaluation factors. Second, since the evaluation was conducted mainly by Skid Steer loader of the company, the evaluation results may be different from those of other companies' Skid Steer loader evaluation results.
