Abstract

This disclosure relates to a working machine having a vehicle which comprises a chassis, a drive motor and a monitoring unit, which is fixed to the vehicle, for outputting operating information and also warning and interference messages for the operation of the drive motor, having a working assembly, in particular concrete pump, which can be transported on the chassis and is supplied with drive energy from the drive motor in a working mode, and having a mobile remote control device, which can be operated remotely from the chassis, for the working assembly. The remote control device comprises a mobile monitoring unit which is designed to output warning and interference messages for the operation of the drive motor.

First claim

What is claimed is:

1. A truck-mounted concrete pump, comprising:
a) a road vehicle comprising a chassis, a drive engine and a control unit, the control unit having a display and being fixed to the vehicle and located in a driver's cab, the control unit configured to output operating information and warning and fault messages for operation of the drive engine;
b) a concrete pump built on the chassis and having a distributor boom connected thereto, in a working mode the concrete pump being supplied with drive energy from the drive engine to feed concrete;
c) a mobile remote-control operable at a distance from the chassis, the mobile remote-control configured to operate the concrete distributor boom and configured to simultaneously output at least one of the warning and fault messages which are output in the driver's cab; and
d) the mobile remote-control further configured for manual operator intervention to change one or more conditions of the drive engine associated with the warning or fault messages.

2. The concrete pump as claimed in claim 1 , wherein the mobile remote-control unit is connected to a vehicle-side interface.

3. The concrete pump as claimed in claim 2 , wherein the mobile remote-control unit is connected to the vehicle-side interface via a wireless transmission link.

4. The concrete pump as claimed in 1 , wherein the control unit fixed to the vehicle and the mobile remote-control unit are configured for actuation in parallel in order to simultaneously display warning and fault messages.

5. The concrete pump as claimed in claim 1 , wherein the mobile remote-control unit has a display device.

6. The concrete pump as claimed in claim 5 , wherein the display device comprises a screen and/or warning lights configured to visually display the warning and fault messages.

7. The concrete pump as claimed in claim 1 , wherein the mobile remote-control unit is configured to output operator control information.

8. The concrete pump as claimed in claim 1 , wherein the warning and fault messages are provided in the form of symbolic or textural representations or acoustic signals or haptic feedback for informing an operator about malfunctions, faults or risks for the operation of the traction engine.

9. The concrete pump as claimed in claim 1 , further comprising an information processor for providing information linked to the warning and fault messages.

10. The concrete pump as claimed in claim 1 , further comprising a transmission that is connectable via a mobile radio network to a control center which is remote from the vehicle, the transmission configured to transmit warning and fault messages and corresponding operating information of the drive engine and/or concrete pump in the working mode.

11. The concrete pump as claimed in claim 1 , wherein at least one the warning and fault messages relates to fuel supply, oil temperature, oil level, coolant level, and/or rotational speed of the drive engine.
