A head guard assembly for heavy equipment according to an embodiment of the present invention includes: a pillar prepared in a vertical direction around a driver seat; and a resonant part which is linked to the outside and an engine room prepared at a lower part of the pillar, and is protruded or recessed at one side of the pillar, so that noise generated by air absorbed into the engine room and noise generated in the engine room are resonated. The head guard assembly for the heavy equipment according to the present invention can improve efficiency of sound-absorbing materials and a resonator etc by neutralizing noise due to engine explosion contributing highly to noise generation, through simple structure changing, such as preparing the protruded, recessed, or hole type resonant part in the pillar. Therefore, the head guard assembly can improve working environment since the head guard assembly can reduce degree of fatigue of a worker by reducing total noise of the heavy equipment without extending the size of the resonator. |
