Weighing system for loads manipulated by lifting equipment
The invention concerns a weighing system for the calculation of the weight of a load that is manipulated by Iifting equipment in which there are components a crane arm (1A) that has one end with an end part (1B) fixed attached to it that through a jointed connector (5) with an axle bearing allows the load to be rotated around an axis of rotation (B, C) relative to the crane arm, characterised in that the system includes: - a detection means (212A, 212B) that detecting the weight of the load that is being manipulated is integrated into a load-sensitive guide pin (35, 35') that forms part of the axle bearing and that can output a signal that is proportional to the effect that is caused by the load, - a power source (506) to provide driving power for the load-sensitive guide pin (35, 35'), - a sensor cable (504) for the transfer of a driving voltage from the power source to the load-sensitive guide pin (35, 35'), - a calculation means (507) that is in signal-transfer connection with the load-sensitive guide pin (35, 35') in order to calculate the weight of the load that corresponds to the signal from the load-sensitive guide pin.
