Development of New-model Trolley Wire Fault Repair Devices
|The trolley wires are the equipment that supplies electricity to the train by making contact with its pantograph. The faults in trolley wires cause localized abrasion so it is necessary to repair them.
This processing requires a high level of skills and is work for which brute strength is also necessary, so depending on the worker it sometimes took a long time or there were variations in the quality of the processing.
Furthermore, we process the trolley wire ends by twisting them in order to ensure that the pantograph can pass through smoothly when two trolley wires are connected to each other. This processing requires a high level of skills and is work for which brute strength is also necessary.
Therefore, we developed the "new-model trolley wire fault repair devices" which can perform both of these jobs with just one tool. The tool we developed has an embedded gear structure so it can be operated with approximately half of the conventional force and now anyone can easily correct the faults in the trolley wires. Furthermore, it is now possible to carry out the processing of the trolley ends with a consistent quality, regardless of the skills of the worker.
