<p>PROBLEM TO BE SOLVED: To confirm a cargo, the frontage of a pallet and so on even during night or in a dark place by fitting a controller whose lamp always irradiates the front end of a fork according to the vertical motion of a lift bracket by the rotation of a tilting drive device. SOLUTION: A potentiometer 10 is fitted at a mast device 3 to detect the height of a fork 9. A tilting drive device consisting of a motor, and an irradiation device 14 consisting of a gear and a lamp are fitted ahead of a head guard 5. The irradiation angle of the irradiation device 14 is calculated and adjusted by a controller so as to indicate the front end of the fork 9. The irradiation angle is calculated, the tilting drive device 11 is rotated so as to turn the lamp 13. The irradiation device always irradiates the front end of the fork 9, it is thus possible to confirm a cargo or a pallet not only at the time of loading and unloading work but also at the time of driving.</p> |
