  • Patent number: 11755011
    Abstract: A method for controlling at least one industrial truck comprising determining a driving job using a superordinate control unit and sending the driving job from the superordinate control unit to a transceiver of the at least one industrial truck. The driving job is transmitted from the transceiver to a vehicle controller. A position of the at least one industrial truck within a previously known route to be driven is determined via the superordinate control unit. An upcoming driving situation is identified using the superordinate control unit and is based on the position of the at least one industrial truck and the driving job. A protective field is generated with a collision protection apparatus, wherein the protective field is monitored by the at least one industrial truck based on the upcoming driving situation even before the at least one industrial truck reaches the driving situation.

  • Patent number: 11597641
    Abstract: An industrial truck (2) and a method for operating the same. The industrial truck includes a load fork (4), a fork back (6) and a plurality of fork arms (8a, 8b), each of which include an arm tip at a free end and an arm root arranged on the fork back. The industrial truck includes a load carrier detection system for a load carrier (20, 30, 40) to be transported, which includes at least one spacing distance measurement sensor (14) provided on the load fork that is configured to detect a spacing distance between the load carrier and the fork back, and one or more monitoring sensors (10, 12) provided on the load fork configured to monitor a predetermined measurement region on the load fork. A processing unit for the sensors is configured to determine a reception of the load carrier picked up by the load fork.

  • Publication number: 20220259022
    Abstract: An industrial truck comprising a vehicle body and a pair of fork prongs. Each of the fork prongs extends from the vehicle body towards a corresponding fork end in a longitudinal direction. The industrial truck comprises a plurality of wheels with which the industrial truck stands and moves on a driving surface in a driven and steered manner. At least one of the wheels is assigned to each of the fork prongs. The industrial truck comprises a lifting mechanism to adjust a height of the fork prongs above the driving surface. The industrial truck comprises at least one detection unit to detect objects located in surroundings of the truck within a detection region and to output corresponding data and a control unit operatively coupled to the at least one detection unit to receive and process the data output by the at least one detection unit.

  • Publication number: 20200391987
    Abstract: An industrial truck comprises a vehicle control, a lifting member, and a drive system configured for automatic operation. A personal safety system comprises a distance measuring apparatus and is configured to detect and evaluate at least one safety zone in front of the lifting member. The distance measuring apparatus is configured to obtain distance data on objects and obstacles within the at least one safety zone. The vehicle control is configured to at least one of deposit and pick up a plurality of load carriers positioned at a predetermined distance from each other. The vehicle control is configured to access the distance data of the personal safety system in order to automatically control the lifting member and the drive system.
