。In a forklift truck equipped with a freev mast having two lift cylinders 5a, 5b, the lift cylinder 5a, 5b is connected between the operating valve 3, which supplies hydraulic pressure from the hydraulic pump 1 to the lift cylinders 5a, 5b, and the lift cylinders 5a, 5b. When the bottom pressure of the cylinder 5a is below the set value, the high speed position 81 is set and hydraulic pressure is supplied to one lift cylinder 5a, and when it exceeds the set value, the low speed position is set to 8□ and hydraulic pressure is supplied to each lift cylinder 5a, 5b. A hydraulic circuit for a forklift truck with a speed change valve 8 interposed therebetween.
