Abstract: A transportation vehicle capable of realizing a cleaning function of an exhaust gas purifying device while suppressing increase in the weight and costs. The transportation vehicle comprises: a diesel engine; a generator; a traveling motor; a grid box that converts the electric power generated by at least one of the generator or the traveling motor into heat to consume the electric power; an exhaust gas purifying device, and a controller configured to, in a case of causing the generator to generate load necessary to increase a temperature of the exhaust gas to a cleaning temperature, if determining that additional electric power additionally generated by the generator can be consumed by the grid box, cause the generator to additionally generate the additional electric power to remove the harmful substances deposited on the exhaust gas purifying device, and causes the grid box to additionally consume the additional electric power.

Abstract: Provided is a haulage vehicle having an air cleaner that is realistic from the viewpoints of fabrication steps and cost aspect. An air cleaner (24) arranged in a haulage vehicle is provided with a swirling flow generator (26), a separator (27) and an outer cylindrical casing (25). The swirling flow generator has a fixed shaft (28) and a plurality of guide blades (29) arranged and shifted from one another over a predetermined angle in a direction in which the guide blades rotate about the fixed shaft, and by the plurality of guide blades, a swirling flow of cooling air is generated. The separator has a flange (32) attached on and along an inner peripheral wall of the outer cylindrical casing (25), an inner cylindrical member (30) arranged on an outer edge of a center bore of the flange, and a collection pocket (31).
