Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] ブーム起伏用シリンダのブーム起立動によって排油され
る側の配管に設けた高圧用リリーフ弁にベント回路を介
して電磁弁を接続し、該電磁弁に低圧用リリーフ弁を接
続して該電磁弁によりブーム角度が掘削作業状態の場合
にはベント回路と低圧用リリーフ弁とが連通される様構
成したことを特徴とするアンローダ。A solenoid valve is connected via a vent circuit to a high-pressure relief valve provided on the pipe on the side of the boom-raising cylinder from which oil is drained when the boom is raised, and a low-pressure relief valve is connected to the solenoid valve. An unloader characterized in that the vent circuit and the low pressure relief valve are configured to communicate with each other when the boom angle is in an excavation work state.
