To provide an authentication system for a high-place work vehicle, which can reduce the execution frequency of authentication during work.SOLUTION: When a power cut-off operation is carried out by an upper power source switch 81 to turn off power, and then a power input operation is carried out by the upper power source switch 81 to turn on power, if the power-off and power-on operations are carried out in a state where a lifting device 20 is not stored, authentication appropriate information based on a last authentication result is maintained, and an operation permissible state is set without carrying out authentication again. On the other hand, if the power-off and power-on operations are carried out in a state where the lifting device 20 is stored, the authentication appropriate information based on the last authentication result is cleared, and authentication is carried out again.SELECTED DRAWING: Figure 3

    【課題】作業中における認証の実行回数を低減することが可能な高所作業車の認証システムを提供する。【解決手段】上部電源スイッチ81による電源切り操作が行われて電源オフとなり、次に上部電源スイッチ81による電源入り操作が行われて電源オン状態となった場合は、これらの電源切り操作および電源入り操作が、昇降装置20が格納されていない状態で行われたときは、前回の認証結果による認証適正情報を維持し、改めて認証を行うことなく、作動許可状態とする。一方、これらの電源切り操作および電源入り操作が、昇降装置20が格納されている状態で行われたときは、前回の認証結果による認証適正情報をクリアし、改めて認証を行う。【選択図】図3
