  • Publication number: 20220022387
    Abstract: 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.
