Abstract
A braking system of an industrial vehicle includes an accumulator accumulating hydraulic oil, a hydraulic oil cooler cooling the hydraulic oil, an electromagnetic switch valve switching between an oil channel for the accumulator that allows supplying the hydraulic oil from a hydraulic pump to the accumulator and an oil channel for the hydraulic cooler that allows supplying the hydraulic oil from the hydraulic pump to the hydraulic oil cooler, and a controller controlling the electromagnetic switch valve to switch from the oil channel for the hydraulic cooler to the oil channel for the accumulator with timing of an increase after a drop in an engine speed when a cargo-handling operation is detected while an oil is at a setting pressure value or less and while the engine speed is at a setting engine speed or less.
