Output device 8 with built-in clutch by water-cooled engine 1
Is driven and the output of the clutch-embedded output extraction device 8 is transmitted to the traveling wheels 3 via the transmission 9 and a differential (not shown), so that the vehicle can be driven. Then, during high-speed traveling or medium-speed traveling, heat exchange by the traveling wind is performed in the radiator 2, and during low-speed traveling or when the vehicle is stopped, the radiator 2

The second generator 15 having a capacity of 300 KVA may be mounted to drive the drainage pumps P3 and P3. As a result, the maximum total drainage amount can be doubled as compared with the conventional example. Further, even if the weight of the second generator 15 increases, if the load falls within the range of the load of the truck-type drainage pump vehicle, the drainage pump P1 is operated by the first generator 5 having a power generation capacity of 300 KVA to generate electricity. The second generator 15 with a capacity of 900 KVA is installed and drainage pumps P2, P3, P3 are installed.

With this configuration, the actual configuration shown in FIG.
A single large-capacity generator 16 having the total power generation capacity of the first generator 5 and the second generator 15 shown in the embodiment is used as a power source for operation, and a plurality of drainage units are used. Since the pumps P1, P2, P3, P4 can be operated, the number of generators used can be reduced to one, and the space on the cargo bed necessary for installing the generators can be reduced to reduce the number of other devices. The loading space can be expanded.
