PROBLEM TO BE SOLVED: To provide an operating machine which enables easy maintenance of a cooling fan disposed between an engine and a radiator.SOLUTION: An operating machine includes: an outgoing tube 52 and a return tube 53 which connect an intercooler 30 with an engine 14, are disposed so as to penetrate through a mounting frame 28 in a machine body interior-exterior direction, and have flexibility and shape holding ability. The mounting frame 28 includes: a body part 38 supporting the intercooler 30 and a support part 39 capable of supporting the outgoing tube 52 and the return tube 53. The mounting frame 28 is formed so as to swing around a rotation axis X, and the support part 39 is formed so as to change its state between a support state where the support part 39 is supported by the body part 38 and a support release state where the support part 39 is released from the support state.
