A boom system for regulating the installation angle of an excavator is provided to perform excavation work in various directions by regulating the installation angle of an excavator variously and to improve stability and safety on work by installing an excavator to a structurally stabilized boom system. A boom system(200) for regulating the installation angle of an excavator comprises: a boom arm(210) installed to heavy equipment and provided with a primary fixed part having pin holes, a secondary fixed part having pin holes, a U-shaped connector(213) having a pin hole to connect with a main body of an excavator and a bracket(214) having a pin hole to fix with a cylinder of an installation member driving cylinder; a boom arm driving cylinder(220) as a double-acting oil pressure cylinder composed of a rod connected to the boom arm and a cylinder installed to heavy equipment to lift up the boom arm; a pair of hinge members(230) formed at the fixed radius of curvature and pinned to the end of the boom arm; a link member(240) composed of a primary connection(241) having a pin hole and a secondary connection(242) having a pin hole and connected to the hinge member; an equipment installation member(250) pinned to the primary fixed part of the boom arm, connected to the secondary connection of the link member and fixed with an excavator(300); an installation member driving cylinder(260) as a double-acting oil pressure cylinder composed of a rod connected to a connecting pin of the hinge member and the link member and a cylinder coupled to the bracket of the boom arm; and an excavator driving cylinder(270) as a double-acting oil pressure cylinder composed of a cylinder(272) connected on a fixed frame and a rod(271) connected to a cylinder connection of the equipment installation member.
