PROBLEM TO BE SOLVED: To enable a radiator to be easily detached and attached independently, to simplify maintenance work and improve workability. SOLUTION: The cooling water passage in an engine body of the construction equipment and the radiator 21 are connected to each other by piping hoses 22A, 22B, and cooling water is circulated in the engine body of the cooling device of the construction equipment. A pipe coupling 28 is provided between the radiator 21 and the piping hoses 22A, 22B, and the pipe coupling 28 connects the piping hoses 22A, 22B to the radiator 21 so that the piping hoses 22A, 22B can be attached and detached. Then the piping hoses 22A, 22B and the radiator 21 are connected to each other through the medium of the pipe coupling 28. COPYRIGHT: (C)2008,JPO&INPIT
