The present invention 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. In addition, the present invention relates to a parallel linkage-type working apparatus for construction equipment which 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. In addition, the present invention relates to a parallel linkage-type working apparatus for construction equipment which, like the related art, has two cylinders for operating a parallel linkage and also has a similar operating relationship to that of the related art, and has a main angle specification for operating the linkage which is similar to a typical work environment, so as to enable even a worker who is a beginner to quickly become accustomed to using the apparatus without any separate training or perceiving a sense of difference. |
