Abstract

In the cooling system of construction equipment equipped with a plurality of heat exchangers including radiators, in providing a pressure-sealed reservoir tank connected in parallel with radiators in the cooling water circulation system between the radiators and engine, said reservoir tank is arranged so as not to protrude above the upper tier heat exchanger, the radiator and oil cooler are arranged lower than the upper tier heat exchanger in a lower tier heat exchangers, and the horizontal width of inter-cooler is made shorter than the horizontal width of radiator and oil cooler forming the tank space laterally to the inter-cooler where the pressure-sealed reservoir tank is arranged on said tank space.
