  "textContent": "Provided is a dump truck capable of switching a destination of supply of hydraulic oil from a hoist cylinder to a fan motor at an appropriate time. A dump truck comprising: a hydraulic pump for discharging a hydraulic oil by a driving force of the engine; a hoist cylinder for raising and lowering a vessel by the hydraulic oil supplied from the hydraulic pump; a fan motor for driving a fan that supplies a radiator with cooling air by the hydraulic oil supplied from the hydraulic pump; a selector valve capable of being switched between a first position for supplying the hoist cylinder with the hydraulic oil discharged from the hydraulic pump and a second position for supplying the fan motor with the hydraulic oil; and a controller configured to, in a case where the selector valve is in the first position, determine whether an inflow pressure of the hydraulic oil flowing into the selector valve is less than a threshold value, and in a case of determining that the inflow pressure is less than the threshold value, switch the selector valve from the first position to the second position.",
