PROBLEM TO BE SOLVED: To provide an engine load control device for a working vehicle that can change a speed reduction rate according to a working mode and switch to a load control mode when an excessive load is applied during work.SOLUTION: The engine load control device 50 for a working vehicle is configured to increase or decrease the speed of the vehicle or lift up and down a working machine 30 according to a load when an engine 21 is overloaded so that the engine speed is maintained at a set engine speed Xs. The control device includes a control execution priority order setting device 52 for setting a control priority order of a control for a loaded vehicle speed and a control for lifting up and down a loaded working machine.COPYRIGHT: (C)2013,JPO&INPIT【課題】作業時に過負荷がかかった場合において、作業形態に応じて減速割合を変更可能とし、負荷制御のモードを切換可能な作業車両のエンジン負荷制御装置を提供する。【解決手段】作業車両のエンジン負荷制御装置において、エンジン負荷制御装置50は、エンジン回転数を設定エンジン回転数Xsに保つように、エンジン21が過負荷となった時の負荷に応じて、車速を増減し、又は作業機30を昇降する構成とし、負荷車速制御と負荷作業機昇降制御との制御優先順位を設定する制御実行順序設定手段52を備える。【選択図】図2
