The cargo handling vehicle 50 basically includes a vehicle body 51, a cargo handling device 52 provided in front of the vehicle body 51, a counterweight 53 provided behind the vehicle body 51, and a cargo handling device 52 and the counterweight 53. Engine 54 provided on the vehicle body 51 between
And an engine cooling device 55 provided on the vehicle body 51 between the engine 54 and the counterweight 53. The engine cooling device 55 includes a radiator 56 connected to a water jacket (not shown) of the engine 54, and a fan 57 provided in front of the radiator 56 and rotated by the engine 54. In such a case, the engine cooling device is installed on the rear side of the vehicle body where it is easy to secure a balance moment. However, in such a device, although the specific gravity of the engine cooling device itself is large, the bulk specific gravity becomes small in consideration of a space for achieving the same. For this reason, the counterweight must be made larger and heavier.
