According to an embodiment of the present invention, a head guard assembly for an industrial vehicle comprises: a pillar vertically positioned to surround a driver′s seat; a roof included in an upper part of the pillar to surround an upper part of the driver′s seat; and a noise reduction part included inside the pillar to reduce the volume of the pillar to change the impedance of engine intake noise generated due to the introduction of air to an engine. According to the present invention, the head guard assembly for an industrial vehicle has the noise reduction part included in a hollow part of the pillar vertically formed to have a long shape and the roof horizontally formed to have a long shape with no interference with other parts such as the engine, a blow hole or the like without deformation of the appearance of heavy equipment. Therefore, multiple noise reduction parts can continuously or discontinuously be included in the heavy equipment occupying a limited space, and the entire noise of the heavy equipment can be reduced by changing the impedance of the engine intake noise such that the degree of fatigue of a worker can be reduced, thereby improving working environment. |
