日本中央铁道公司和Ishikawaiima-Harima重工业公司合作研制出一种更换铁轨时使用的机器人,该机器人可用来拧紧或拆除固定铁轨的螺钉。据日本中央铁道公司讲,用机械化方法更换铁轨可节省约30％的劳动力。 当铁轨的累积载重或磨损程度超过预期水平时,必须及时更换它。通常在1.5公里的路段上更换铁轨大约需要120名工 Japan’s Central Railways Corporation and Ishikawaiima-Harima Heavy Industries Co., Ltd. have worked together to develop a robot that can be used to change tracks that can be used to tighten or remove the screws that secure the tracks. According to the Japan Central Railways Corporation, the mechanized method of replacing rails can save about 30% of the workforce. It must be replaced promptly when the cumulative load or wear of the rails exceeds the expected level. It usually takes about 120 workers to change tracks on a section of 1.5 kilometers
