ENERGY-SAVING OPERATION SUPPORT DEVICE OF WORKING MACHINE
PROBLEM TO BE SOLVED: To report accurate operation evaluation according to an operation state.SOLUTION: An energy-saving operation support device is mounted on a working machine which includes an HST travel circuit performing closed circuit connection between a hydraulic pump 210 driven by an engine 1 and hydraulic motors 211, 212 driven by discharge oil from the hydraulic pump 210. The energy-saving operation support device includes: a working mode dial 5 which selects at least one of a high load mode and a low load mode of which the maximum rotational frequency of a required rotational frequency of the engine 1 is lower than the high load mode; an HST controller 3 which evaluates whether operation of an operator is energy-saving operation; and a monitor 4 which reports that operation of an operator is evaluated to be energy-saving operation by the HST controller 3 when selecting one of the low load mode and the high load mode by the working mode dial 5.
【課題】運転状態に応じた正確な運転評価を報知する。【解決手段】エンジン１により駆動される油圧ポンプ２１０とその油圧ポンプ２１０からの吐出油で駆動される油圧モータ２１１，２１２とを閉回路接続したＨＳＴ走行回路とを備える作業機械に搭載される省エネ運転支援装置において、少なくとも高負荷モードと、高負荷モードよりもエンジン１の要求回転数の最高回転数が低い低負荷モードとのいずれか一方を選択する作業モードダイヤル５と、オペレータの運転操作が省エネ運転操作であるか否かを評価するＨＳＴコントローラ３と、作業モードダイヤル５により低負荷モードおよび高負荷モードの一方が選択された場合、ＨＳＴコントローラ３によってオペレータの運転操作が省エネ運転操作であると評価されたことを報知するモニタ４とを備える。【選択図】図２
