Industrial truck and method for operating the same

A method for operating an industrial truck that includes a load fork for picking up a load carrier, the load fork having a fork back and a plurality of fork arms arranged on the fork back, each of the plurality of fork arms having an arm tip at a free end and an arm root arranged on the fork back, the method comprising:

• detecting a spacing distance between the load carrier and the fork back with a spacing distance measurement sensor of a load carrier detection system provided on the load fork;
• and
• monitoring a predetermined measurement region on the load fork with at least one monitoring sensor of the load carrier detection system, said at least one monitoring sensor being arranged in a respective one of the plurality of fork arms in a region of the arm tip of the respective one of the plurality of fork arms, the at least one monitoring sensor having an upwardly oriented measurement region configured to detect a presence of the load carrier in a region of the arm roots of the plurality of fork arms;
• wherein sensor signals are transmitted by the spacing distance measurement sensor and by the monitoring sensor to a processing unit of the load carrier detection system, and
• wherein the processing unit is configured to determine, based on signals sent to the processing unit by the spacing distance measurement sensor and the monitoring sensor, a reception of the load carrier being picked up by the load fork.
