Definitions
- the charging switch 15 may be provided inside the cab 6, for example.
- charging switch 15 can be operated immediately after connecting or disconnecting power supply cable 91 at the position where the operation was performed. Therefore, from this point of view, it is preferable to provide the charging switch 15 in the power receiving box 13. Further, the charging switch 15 may be provided both in the cab 6 and in the power receiving box 13.
