WORKING MACHINE PROVIDED WITH CAPACITOR

摘要

PROBLEM TO BE SOLVED: To satisfy charge storing conditions required for each work while reducing the size and weight of a capacitor. SOLUTION: A working machine line a shovel is equipped with a generator 18 and motor-operated actuators 39... for generating the power to operate working members by using the electric power generated with the generator 18. A plurality of capacitors 14A, 14B are installed as the means for charging and discharging electric power. According to demand power, contents of work, etc., the capacitors to be used can be switched selectively.
