  • Weighing system for loads manipulated by lifting equipment
    Patent number: 9708165
    Abstract: A system includes: a detection means that detecting the weight of the load that is being manipulated is integrated into a load-sensitive guide pin 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 to provide driving power for the load-sensitive guide pin, a sensor cable for the transfer of a driving voltage from the power source to the load-sensitive guide pin, a calculation means that is in signal-transfer connection with the load-sensitive guide pin in order to calculate the weight of the load that corresponds to the signal from the load-sensitive guide pin.
