Abstract: A support force measurement apparatus for determining a support force on a support element of a support structure of a movable working machine. The measurement apparatus has at least one measurement element and a support leg. The measurement element is connected to a deformation body capable of being deformed with an effect of the support force, so as to form a sensor and send a signal proportional to the support force. The support leg has the sensor and is movably connected to the support element. The support element comprises a cable connection, and the cable connection is constructed in a manner of guiding electrical energy and is used for sending the signal proportional to the support force to an analysis apparatus in a machine. The support element in the support leg and the sensor are provided with electromagnetic interfaces.

Abstract: A load cell for detecting the supporting force transmitted by a load-bearing support element is provided. The load cell forms a measuring portion of the support element, which deforms under the supporting force and transverse forces in a direction deviating from the supporting force to form part of the support element with the same. A plurality of thin-film resistors are arranged at the measuring portion, and exhibit a reaction proportional to strain and whose reactions proportional to transverse forces cancel each other.
