Abstract

A clutch control device for an industrial vehicIe includes: a braking force detection device that detects braking force of the industrial vehicle; a speed stage detection 5 device that detects a set speed stage of a transmission; a clutch control device that controls engagelrelease of a forward clutch so that the forward clutch is released when a clutch cut off condition is judged to be satisfied based upon braking force ofthe industrial vehicle detccted by the braking force detection device; and a switching device that automatically switches the clutch cut off condition in the clutch control device based upon a set sped 10 stage of the transmission detected by the speed stage detection device.
