A forklift truck having the structure controlling the tilting angle of a mast is provided to reduce the falling risk of loaded stuff by controlling the tilting angle of the mast. A forklift truck having the structure controlling the tilting angle of a mast comprises: a tilting cylinder(100) providing the hydraulic force in order to compel the tilting operation of the mast; a hydraulic relief valve(200) and a solenoid valve(300) connected to the tilting cylinder in order to control the output flow rate provided to the tilting cylinder; and a tilting angle control part(500) connected to the tilting cylinder and the solenoid valve in order to control the tilting angle of the mast by sensing the relative tilting angle of the mast based on the rotation angle of the tilting cylinder. The tilting angle control part includes an angle sensor(520), a flow detection sensor(550) and a controller(510). |
