PURPOSE: A muffler bracket for heavy equipment is provided to effectively reduce vibration caused by high-pressure exhaust gas by supporting the center of both sides of a muffler. CONSTITUTION: A muffler bracket for heavy equipment comprises a connection bracket(110) and a fixing bracket(130). The connection bracket is fixed to a side of a muffler by being installed on a horizontal line(L1) passing through the gravity point(P) on the side of the muffler so that the muffler bracket supports the center of both sides of the muffler. The fixing bracket is coupled to the connection bracket via a damper(120) that is composed in pair having a symmetric structure around a vertical line(L2) passing through the gravity point. The fixing bracket is fixed to a structure(20) provided in heavy equipment.
