로울러기의 安全裝置에 관한 硏究 = A Study on the Safety Device of the Roller

다국어 초록 (Multilingual Abstract)

An accident by roller is due to safety device unfixed otherwise bad safety device, as a narrowness accident by defect of safety device.
Although a roller sticking with sudden stop device as per relevant regulations of the industrial safety & health law, industrial accident could not be prevented basically while prompt rescue was impossible and in consequence, industrial accident measures for precaution was insufficient.
Accordingly, while bringing up development of roller safety device to be imminent and developing safety device of roller reversion, and after experiment & application to industrial came to a conclusion as hereunder.
1. As newly developed reversion type of roller safety device revolves as much as only 1/33 of the circumference, which is considerably short comparing with stopping distance 1/6.51 of the circumference of sudden-stop type of safety device, and stop reverses immediately, can prevent from roller accident beforehand and raise a credibility of safety device thence minimize damages by saving the wounded promptly, in case possible occurrence of accident.
2. Developed reversion safety device is installed in roller shortly and convenient to reoperate after operating safety device.
3. Accident by roller occured due to safety device unfixed, or irrational standards of efficiency test on the industriasl safety & health law although installed, and therefore shalll strengthen the standards of roller efficiency test.
