<P>PROBLEM TO BE SOLVED: To provide a forklift capable of controlling the aggravation of fuel consumption by reducing the pressure loss of an oil pressure supply line. <P>SOLUTION: The forklift includes a forklift body having front wheels and rear wheels, a fork liftably supported at the front of the forklift body through a mast, a lift cylinder 17 capable of lifting the fork, a hydraulic pressure supply line 31 capable of supplying a hydraulic pressure to the head-side chamber R1 of the lift cylinder 17, a hydraulic pressure discharge line 34 capable of discharging the hydraulic pressure from the rod-side chamber R2 of the lift cylinder 17, and a switching valve 35 provided in the hydraulic pressure discharge line 34. When a cargo load on the fork exceeds a load weight limit, a control device 26 causes the switching valve 35 to change the pressure balance between the hydraulic pressure in the head-side chamber R1 of the lift cylinder 17 and the hydraulic pressure in the rod-side chamber R2 thereof to limit the operation of the lift cylinder 17. <P>COPYRIGHT: (C)2013,JPO&INPIT |
