- 엔진과, 이 엔진에 의해 구동되는 유압펌프와, 상기 유압펌프로부터의 토출유(吐出油)에 의해 작동되는 유압 액추에이터와, 엔진과 조합되는 전동기와, 엔진에 의해 구동되는 발전기와, 상기 발전기에 의한 발전전력을 충전하는 배터리를 구비한 다기능형 건설기계에 있어서,조작레버나 조작패널에 설치된 파워업(power up)용 스위치의 조작시에 컨트롤러는, 유압펌프의 흡수토크와 엔진의 정격출력점 토크를 비교하여, 그 흡수토크가 그 정격출력점 토크보다도 낮다고 판단한 경우에, 엔진의 회전수를 일정하게 제어하고, 그 정격출력점 토크근방까지 가도록 도와주는 토크를 출력하도록 전동기의 출력토크를 제어하는 다기능형 건설기계.
- 제2항에 있어서,파워업용 스위치의 조작시에 컨트롤러는, 유압펌프의 흡수토크와 엔진의 정격출력점 토크를 비교하여, 그 흡수토크가 그 정격출력점 토크를 포함한 그 근방이라고 판단한 경우에, 엔진의 회전수를 일정하게 제어하고, 그 정격출력점 토크를 초과하여 도와주는 토크를 출력하도록 전동기의 출력토크를 제어하는 다기능형 건설기계.
