PROBLEM TO BE SOLVED: To improve cooling performance, and decrease noise of a refrigerator, a cooling fan and an engine by effectively cooling an engine system and an oil pressure system mutually. SOLUTION: An engine room ER for closely surrounding a transverse engine 8 is arranged on a front side of a counter weight 27 of a construction machine. At least either one first cooler 100a of coolers 100 such as an oil cooler 50, a radiator 40, and an inter-cooler 1c, a first cooling fan 52, and a first driving means 52a(52d) are provided on a side part of an engine room ER and a forward part of the counter weight 27 in an outside of the engine room. Furthermore, a second cooler 100b other than the first cooler 100a, a second cooling fan 53, and a second driving means 52a(52d) are arranged on a forward part of the other side part 1b of the construction machine. Accordingly, it is possible to increase intake of cooling air, and improve view on a forward side of the other side part 1b of the construction machine.
