Abstract
A boom (1) is used for receiving loads on the end thereof. The boom (1) has a metal boom hollow profile (2) extending along a boom longitudinal axis (3), and also a reinforcing layer (7) made of a fiber-plastic composite, connected to the boom hollow profile (2) at least in sections. At least one sensor element (12) is arranged in the region of the reinforcing layer (7). The sensor element (12) is used to detect strains in the boom (1).
Claims24
A boom (1) for receiving loads on the end thereof comprising:
- an inner wall (8) defining a metal boom hollow profile (2) extending along a boom longitudinal axis (3);
- a reinforcing layer (7) made of a fiber-plastic composite, disposed within the boom hollow profile (2), present at least in sections;
- an electrically insulating intermediate layer coupled between the reinforcing layer and the inner wall (8);
- and
- at least one sensor element (12) arranged in the region of the reinforcing layer (7) to detect load forces acting on the boom (1).
A boom (1) for receiving loads on the end thereof comprising:
- a metal boom hollow profile (2) extending along a boom longitudinal axis (3);
- a reinforcing layer (7) made of a fiber-plastic composite, connected to the boom hollow profile (2), present at least in sections, wherein the reinforcing layer (7) is arranged as a reinforcing lining in a hollow cavity defined by the boom hollow profile (2);
- and
- a sensor element group comprising a plurality of strain gauges interconnected as a measuring bridge, the sensor element group arranged on the reinforcing layer.
A boom for receiving loads on the end thereof, the boom comprising:
- a metal boom hollow profile comprising a plurality of inner walls and extending along a boom longitudinal axis;
- a reinforcing layer made of fiber-plastic composite and connected to at least one of the inner walls of the boom;
