Definitions

  • the invention relates to an industrial truck with load-carrying devices for picking up long goods.
  • the industrial truck includes a safety controller that has at least one monitoring sensor and forms at least one protective field using this monitoring sensor.
  • the disadvantage of this prior art is that the industrial truck with load-carrying devices for picking up long goods does not have a safety control that meets the special requirements of an industrial truck with load-carrying devices for picking up long goods to a desirable extent.
  • the invention therefore had the task of creating such an industrial truck without this disadvantage.
  • the industrial truck according to the invention has a long goods detection device for detecting long goods. It also has a safety controller, which in turn has at least one monitoring sensor and uses this monitoring sensor to form at least one protective field.
  • the safety control is operatively connected to the long goods detection device and is set up so that it influences the at least one protective field depending on long goods detected by the long goods detection device.
  • the protective field can also be referred to as a monitoring field. It prefers to move with the industrial truck.
  • the protective field is preferably part of the detection range of the monitoring sensor.
  • the safety control is preferably set up in such a way that when approaching vehicles or people are detected - preferably by means of the at least one monitoring sensor - the industrial truck is brought into a safe state as soon as the required minimum distances are not reached and/or as soon as vehicles or people approach reach the at least one protective field. Transferring the vehicle to a safe state can mean reducing the driving speed or stopping the truck. It can also mean that movement of the load-carrying means relative to the industrial truck is slowed down or stopped. Approaching vehicles or people can also be those who are standing still and to whom the industrial truck is approaching.
  • the safety control can be set up so that if non-moving objects, such as walls or shelves or parked goods, are detected, the industrial truck is brought into a safe state as soon as necessary Minimum distances are not exceeded and/or an object enters a protective field.
  • an industrial truck with load-carrying devices for picking up long goods can be created with a safety control that meets the special requirements for an industrial truck with load-carrying devices for picking up long goods to a desirable extent.
  • the protective field only needs to be as large as is actually required, depending on the long items being picked up. In this way, particularly smooth operations can be ensured while maintaining a high level of protection.
  • the monitoring sensor may include a personal protection scanner.
  • the load-carrying means can include, for example, a lifting fork or a loading platform.
  • the industrial truck can be designed as a forklift.

  • the tines are preferably spaced so far apart that they are arranged outside the wheel arms when viewed from above, or a distance adjustment device is provided for the tines which allows this arrangement. The large distance between the tines that is achieved or can be achieved in this way can result in a particular suitability for picking up long goods.
  • the industrial truck preferably has a chassis.
  • the chassis can be “U” shaped.
  • the two legs of the “U” shape can each be formed by a wheel arm.
  • the industrial truck can be designed as a reach truck.

  • the long goods can be a load that is longer than 1200 mm.
  • the long goods can be a load which, when picked up on the load-carrying means and in the ready-to-drive state of the industrial truck (in the case of a reach truck, preferably with the reach truck pushed in), stands beyond the contour of the industrial truck, so that there is an overall contour of the industrial truck and load that is greater than the contour of the truck without load.
