RADIATOR PIPING STRUCTURE OF CONSTRUCTION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide the radiator piping structure of construction equipment to reduce the size of a revolving super structure without needing to form a space for preventing the occurrence of interference at the periphery of a cooling water supply piping and simplify the fixing structure of a cooling water supply piping. SOLUTION: A cooling water supply piping 5 to supply cooling water from a radiator 3 to an engine 2 is divided into two sections. A coupling means 6 is arranged at a revolving frame 1 arranged between the engine 2 and the radiator 3. The radiator 3 is connected to the coupling means 6 through a first cooling water supply piping 5a, and the coupling means 6 and the engine 2 are interconnected through a second cooling water supply piping 5b.
