The present disclosure relates to a parallel linkage-type working apparatus for construction equipment in which a parallel lever and a parallel link operate to prevent a working tool from bending inward so that, even if the working tool is raised, a tilting phenomenon in which the working tool is inclined inward may be prevented, and an amount of change in posture of the working tool at each height may be reduced. Also, the parallel linkage-type working apparatus is capable of increasing excavation ability or power with a posture on the ground surface by supplying a larger amount of hydraulic fluid at one time when working hydraulic pressure is supplied to each cylinder head, in comparison with a case in which working hydraulic pressure is supplied to a cylinder rod.
