たことを特徴とする建設機械の消音装置。 The engine is mounted on the side opposite to the operator's cab on the upper revolving structure so that the engine crankshaft is parallel to the longitudinal direction of the upper revolving structure, and the counterweight is attached to the rear end of the upper revolving structure. For construction machinery with an air passage drilled and a sound absorbing material affixed to the inside of the air passage, a radiator with an oil cooler is installed separately from the engine from the outside of the counterweight for the upper revolving body. The construction is characterized in that an air passage communicating with the counterweight is bored in the counterweight, and a partition plate member is provided between the engine and the air passage of the counterweight, thereby making it possible to block engine noise. Mechanical silencer.
