PURPOSE: An arrangement structure of a main control valve for heavy construction equipment is provided to simplify the arrangement structure of a hydraulic hose and an electric wire by arranging a main control valve to be adjacent to a hinge unit of a tilting cabin. CONSTITUTION: An arrangement structure of a main control valve for heavy construction equipment comprises a main control valve housing unit(11). The main control valve housing unit is arranged to be adjacent to a hinge unit of a tilting cabin and receives a main control valve(5) in an outer vehicle body(10) of an engine room(1). The top wall and/or the side wall of the main control valve housing unit are opened. A protruded wall is formed along the edge of the top and inner side walls of the main control valve housing unit.
