Description
ンストップリレー35をONとし、バッテリーリレー29のリレーコイル30の励磁を解除してバッテリーリレー29をOFFとすることによりエンジンを停止し、同時に切換弁37に切り換えて信号を出力してパイロットポンプをドレンタンクに接続するように構成している。
を起動してエンジンを始動する。従って、メインの油圧ポンプ(図示せず)がエンジンにより駆動され、作動油圧回路は動作可能となる。
4 キャビン
22 コントローラ
23 乗降口
24 ゲートバー
25 ゲートロックスイッチ
Claims (2)
- 建設機械のキャビンの乗降口を開閉するゲートバーと、該ゲートバーが前記乗降口を開放するゲート開位置に作動されたときゲート開信号を出力し、前記乗降口を閉鎖するゲート閉位置に作動されたときゲート閉信号を出力する位置検出手段と、該位置検出手段からのゲート開信号により前記建設機械のエンジンを停止するエンジン停止手段とを備え、前記位置検出手段よりゲート開信号が出力されたときは所定時間経過後に前記エンジンを停止させるようにしたことを特徴とする建設機械のエンジン制御システム。
- 上記位置検出手段からのゲート閉信号により上記エンジンを始動するエンジン作動手段を設け、上記ゲート開信号によりエンジンを停止させた後、上記ゲートバーをゲート閉位置に作動したときは前記エンジンを自動的に始動させるようにしたことを特徴とする請求項1記載の建設機械のエンジン制御システム。
