The lifespan of cranes depends greatly on the total number of lifts and the amount of load that they handle. Load is commonly measured with strain gauges, which are glued to the measured object or integrated to load transducer. Elasto-magnetic (EM) phenomenon is an interesting non-contact method to measure load, which still needs further investigations to take full advantage of its potential. Goal of this study was to analyze the applicability of EM-method for load measurement in crane applications. The suitability was studied by performing laboratory tests to certify the relationship between sensor response and applied load. The EM-phenomena was found to work well in the capacity range of small cranes. There are also good possibilities to scale up the sensor for heavy loads.
