A support force measurement apparatus for determining a support force on a support element of a support structure of, specially, a movable working machine. The measurement apparatus comprises at least one measurement element (10) and a support leg (9). The measurement element (10) 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 (9) comprises 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 (93) in a machine. The measurement apparatus is characterized in that the support element in the support leg (9) and the sensor are provided with electromagnetic interfaces (50, 51). The measurement element (10) supplies, by means of electromagnetic induction, electrical energy from the machine through the electromagnetic interfaces (50, 51), and is connected to a cable which transmits, by means of electromagnetic induction, the signal proportional to the support force from the measurement element (10) to the support element. |
