Construction machine

摘要

The present disclosure relates to a construction machine having an undercarriage; a superstructure rotatably supported relative to the undercarriage by a revolving roller connection; and a control system, wherein measuring devices are arranged in the revolving roller connection for the force measurement in the directions of pulling and compression, and the control system determines the force in the axis direction of the axis of rotation as well as the torque which is caused by the eccentricity of the force with respect to the axis of rotation from the detected measured values of the measuring devices. From this, improved monitoring of the operational safety and stability of such a construction machine is achieved.

主权项

1. A construction machine comprising:
an undercarriage; a superstructure rotatably supported relative to the undercarriage about a vertical axis by a revolving roller connection; one or more force measuring devices arranged in a region of the revolving roller connection; and a control system receiving information from the one or more measuring devices including a ring-shaped measuring element coupled to the revolving roller connection and determining one or more resulting forces in an axial direction and perpendicular to the axis of rotation based on the information, the control system further determining an equivalent torque caused by eccentricity of the one or more resulting forces relative to the vertical axis.
