PURPOSE: To shorten the trail radius of a turnable body by a method wherein a radiator for engine cooling water is arranged at the front part of the turnable body and a fan is provided near the radiator and the fan and the fan-fitting part of an engine are connected through a power transmission means.
CONSTITUTION: The wheel type hydraulic shovel is equipped with the engine 5, which is located in the center line 8 being in keeping with the turning center of the turnable body 3, and the power transmission means 7 to transmit the power of the engine 5 to a wheel 2. The radiator for engine cooling water 13 is arranged at the front part of the turnable body 3 and the fan 14 is provided near the radiator 13 in the shovel described above. And the fan 14 and the fan-fitting part 9 provided to the engine 5 are connected through the power transmission means 15. According to the above-metioned arrangement, the trail radius R 2 of the turnable body 3 can be shortened as compared that of the usual ones and at the same time the cooling efficiency of the radiator 13 during running can be improved.
