Abstract—Energy harvesting using a piezoelectric energy harvester (PEH) from the linear vibration of a crane system is presented in this paper. The PEH is designed in the form of a piezoelectricity lever-arm mechanism, and mounted in the midpoint of the top beam of the crane framework through a spring. Two concentrated moving masses traversing on the top beam of the crane framework excite the PEH and result in useful electrical energy. The numerical results show the electric power can be harvested up to 0.5 W, 37.5 W and 4.7 mW in axial, vertical and lateral displacements, respectively with a span of 12 m of the top beam of the crane framework at the trolley speed of 3.7 m/s, and the payload mass of 1200 kg.
