Abstract
A method for monitoring a load, which load acts on a discharge arm of a construction machine for conveying construction material and/or thick material, includes the steps: a) detecting a current angle value of a joint angle of a joint device of an arm unit relative to a joint axis; b) detecting a current pressure value of a hydraulic pressure of the arm unit to which a hydraulic device of the arm unit is subjected and/or a current force value as a function of the pressure value; c) forming a current value pair of the arm unit, in which value pair the current angle value resulting from step a) and the current pressure value or force value resulting from step b) are related to one another in order to monitor the load acting on the discharge arm on the basis of the current value pair.

A method for monitoring a load that acts on a discharge arm of a construction machine for conveying construction material and/or thick material, the method comprising the steps of:
- a) detecting a current angle value of a joint angle of a joint device relative to a joint axis, wherein the joint device pivotably movably mounts an arm member of an arm unit of the discharge arm relative to a machine base of the construction machine, or relative to a further arm member of a further arm unit, about the joint axis;
- b) detecting a current pressure value of a hydraulic pressure of the arm unit to which a hydraulic device, for pivotably adjusting the arm member relative to the machine base or the further arm member about the joint axis, is subjected, and/or detecting a current force value as a function of the pressure value;
- c) forming a current value pair of the arm unit, in which value pair the current angle value resulting from step (a) and the current pressure value or force value resulting from step (b) are related to one another, in order to monitor the load acting on the discharge arm on the basis of the current value pair.
A construction machine for conveying construction material and/or thick material, comprising:
- a discharge arm upon which a load acts, the discharge arm having a plurality of arm units,
- wherein each arm unit has an arm member, a joint device which pivotably movably mounts the arm member relative to a machine base of the construction machine or relative to a further arm member about a joint axis of the arm unit, and a hydraulic device for pivotably adjusting the arm member relative to the machine base or the further arm member about the joint axis,
- wherein each arm unit further has an angle detection device and a pressure detection device;
- and
- an electronic control device operatively configured to:
- a) detect, via the angle detection device, a current angle value of a joint angle of the joint device relative to the joint axis;
- b) detect, via the pressure detection device, a current pressure value of a hydraulic pressure of the arm unit to which its hydraulic device is subjected and/or a current force value as a function of the pressure value;
- and
- c) form a current value pair of the arm unit, in which value pair the current angle value resulting from (a) and the current pressure value or force value resulting from step (b) are related to one another in order to monitor the load acting on the discharge arm on the basis of the current value pair.
