摘要： An overhead line system includes a plurality of support posts, an overhead line supported by the support posts, a lifting device with which the overhead line is liftable, a suspension device that is connected to the overhead line and is movable in the air as the lifting device winds the overhead line, and a control device. The control device controls the lifting device so as to reduce tension when a predetermined condition relating to a tension abnormality of the overhead line is satisfied.

摘要： In an overhead line system, a first moving device is movable in the air between a first support post and a second support post. A first overhead line is stretched from the first moving device and connected to the first lifting device via the first support post. A second overhead line is stretched from the first moving device and connected to the second lifting device via the second support post. A second moving device is movable in the air between a third support post and a fourth support post. A third overhead line is stretched from the second moving device and connected to the third lifting device via the third support post. A fourth overhead line is stretched from the second moving device and connected to the fourth lifting device via the fourth support post. A suspension device is connected to the first moving device and the second moving device.
