On the other hand, in the cooling water circulation system 6 of the radiator 2.
Is provided with an auxiliary radiator 12 provided with a cooling fan 11. The cooling fan 11 is either an electric motor type driven by electric power supplied from the generator 5 or an engine drive type driven by the water cooling engine 1 via a fan belt (not shown) like the cooling fan 7 of the radiator 2. Is adopted. In addition, when selecting the generator 5, a generator having a speed as high as possible has a larger generating capacity and can be reduced in weight.
In the case of A, a 60 Hz, 4-pole AC generator (weight: 930 Kg), which is the lightest and has the largest power generation capacity, is used, which contributes to weight reduction of mounted devices. Incidentally, the power generation capacity is 300K.
In the case of VA, the weight is 15 for an AC generator with 60Hz and 6 poles.
It will be 00 kg. As described above, by increasing the speed of the generator 5 and reducing the weight thereof, the maximum load capacity of the truck-type drainage pump vehicle can be suppressed to less than 20 tons, and the vehicle can be driven on the general road without permission.

By driving the cooling fan 11 attached to the auxiliary radiator 12 by the power supplied by the auxiliary radiator 12, heat is also exchanged in the auxiliary radiator 12 by blowing the cooling fan 11. That is, the amount of heat exchange in the auxiliary radiator 12 is added to the amount of heat exchange performed by the ventilation of the cooling fan 7 in the radiator 2, and the heat exchange capacity when the vehicle is stopped can be increased. For this reason,
Together during drainage operation at the time the vehicle is stopped for a long time continuous operation of the water-cooled engine 1 at the maximum output speed, to cut off power transmission to run Gyowa 3 in clutch-containing output extraction device 8, clutch-containing output extraction device By driving the generator 5 with the maximum output of 8, the drainage pumps P, P ...
