Each electric circuit for the drives of the operating gantry crane is connected through a DC link. Surplus kinetic energy, such as that produced during braking of the crane or lowering of the lifting gear, is converted into electricity and fed back into the grid. This energy can then be used for other purposes, either within the storage facility or by other users. Electric power consumption can be reduced by as much as 40% compared with conventional drive systems, says Kasto.
Kasto’s storage systems cut energy use by up to 40%
Kasto has developed an energy recovery and storage system for its German-built industrial warehouses used for the automated storage and retrieval of bar, tube, sheet, plate and other materials. The technology enables surplus kinetic energy to be converted into electricity and stored temporarily for later use, as needed. Operating and investment costs are therefore reduced, as are CO2 emissions.
