Method of operating a lift truck with a moveable mast and such a lift truck for carrying out this method

摘要

The fork lift truck operating process involves forcibly setting the angle (32) of the lifting mast (14) by means of a first angle drive, and the angle (34) of the forks (28) by a second angle drive, measuring these relative to the vertical and horizontal respectively, so that the movement of the forks in space is in the direction of the measured angle when the mast drive moves them up or down (20).
