To improve fuel consumption while satisfying the request of cycle time, in a specially-equipped vehicle provided with a hydraulic device for repeating an operation of one cycle including a plurality of steps.SOLUTION: A refuse collecting vehicle 1 comprises: a variable discharge-amount pump which actuates by the power of an engine taken out by a power take-out device and has a pump rotation number region where the discharge amount is fixed even when the pump rotation number increases; and an engine control device which controls the engine with the engine rotation number actuating the variable discharge-amount pump in the pump rotation number region where the discharge amount is fixed. The engine control device determines whether or not loads of a sliding cylinder 13 and an oscillating cylinder detected by a load detection device are equal to or more than a reference load, and, when it is determined that the loads are less than the reference load, controls the engine rotation number to be a first rotation number larger than a prescribed rotation number, and, when it is determined that the loads are equal to or more than the reference load, controls the engine rotation number to be a second rotation number larger than the first rotation number.SELECTED DRAWING: Figure 1

    【課題】複数の工程を含む一サイクルの動作を繰り返し行う油圧装置を備えた特装車において、サイクル時間の要求を満たしつつ燃費を向上させる。【解決手段】塵芥収集車1は、動力取出装置によって取り出されるエンジンの動力により作動し、ポンプ回転数が上昇しても吐出量が一定であるポンプ回転数領域を有する可変吐出量型ポンプと、吐出量が一定であるポンプ回転数領域で前記可変吐出量型ポンプを作動させるエンジン回転数でエンジンを制御するエンジン制御装置と、を備える。前記エンジン制御装置は、負荷検出装置により検出された摺動シリンダ13および揺動シリンダの負荷が基準負荷以上か否かを判定し、前記負荷が前記基準負荷未満と判定したときにはエンジン回転数を所定回転数よりも大きい第1回転数に制御し、前記負荷が前記基準負荷以上と判定したときには前記エンジン回転数を前記第1回転数よりも大きい第2回転数に制御する。【選択図】図1
