| Abstract |
In the event of loss of roadbed on an electric railway line due to typhoon or heavy rain damage caused by abnormal weather, or damage to a subway pole due to an unexpected train derailment, installation of catenary poles for emergency recovery is necessary to restore the electric railways. Conventional emergency catenary poles are made of steel, so they are very heavy, and the length per unit is large, making transportation and installation inconvenient. Also, there is a risk of industrial accidents due to workers' musculoskeletal disorders. In this study, we developed an emergency recovery catenary pole using aluminum, a lightweight material, and researched and developed a slimmer rail fastening device that can also be applied to concrete ballast. The developed product underwent factory testing and reference testing, was assembled and installed on a field test, and then a safety test was performed.
The product developed is expected to minimize disruption to train operations and prevent industrial accidents for related workers by safety and quickly restoring electric railways. |
