INDUSTRIAL TRUCK WITH A LOAD SUPPORTING MEANS

Abstract

An industrial truck with a load supporting means, a sending and receiving unit, the sending and receiving range of which is directed towards a region of the load supporting means and towards a region in front of the load supporting means, and a control unit, which activates the sending and receiving unit for the reception of data from external senders, a sensor being provided which detects a load on the load supporting means and triggers an activation of the sending and receiving unit via the control unit when the sensor has detected a load, characterised in that the sensor is integrated into a housing for the sending and receiving unit.

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

One preferred example of realisation is explained in more detail by means of the figures in the following.

FIG. 1 shows an industrial truck with a RFID sending and receiving unit with an integrated element for the recognition of fork occupancy.

FIG. 2 shows a sending and receiving unit integrated into the mast, and

FIG. 3 shows a schematic construction of a sending and receiving unit,

Claims

1. An industrial truck with a load supporting means (20, 22), a sending and receiving unit (34), the sending and receiving range of which is directed towards a region of the load supporting means (20, 22) and towards a region in front of the load supporting means (20, 22), and a control unit (36), which activates the sending and receiving unit (34) for the reception of data from external senders, a sensor (38) being provided which detects a load on the load supporting means (20, 22) and triggers an activation of the sending and receiving unit (34) via the control unit (36) when the sensor (38) has detected a load, characterised in that the sensor is integrated into a housing (24) for the sending and receiving unit (34).

2. Industrial truck according to claim 1, characterised in that a RFID sending and receiving unit is provided as the sending and receiving unit (34).

3. Industrial truck according to claim 1, characterised in that RFID transponders are provided as external senders.

4. Industrial truck according to claim 1, characterised in that the control unit (36) activates the sending and receiving unit (34) for the reception of data for a predetermined period of time, when the sensor (38) has detected a load.

5. Industrial truck according to claim 1, characterised in that the sensor (38) for detecting a load (30) detects an obstacle on the load supporting means (22) on the basis of optical signals.

6. Industrial truck according to claim 1, characterised in that the sensor (38) for detecting a load (30) detects an obstacle on the load supporting means (22) on the basis of ultrasound signals.

7. Industrial truck according to claim 1, characterised in that the housing (24) is fixed in the region of the load supporting means (22).

8. Industrial truck according to claim 7, characterised in that the housing (24) is fixed on a vehicle body.

9. Industrial truck according to claim 7, characterised in that the housing (24) is fixed on a mast.

10. Industrial truck according to claim 7, characterised in that the housing (24) is fixed in the centre between the load supporting means.

11. Industrial truck according to claim 7, characterised in that the housing (24) is fixed below a field of sight of a driver.

12. Industrial truck according to claim 1, characterised in that the load supporting means (22) has a load fork (22) and the sensor is realised as a fork occupancy sensor (38).

13. Industrial truck according to claim 1, characterised in that the control unit (36) is integrated into the housing (24) for the sending and receiving unit.
