THE DRIVE FOR DIGITAL CONTROL

The installation of digital drive controls on new or retrofitted dockside container cranes has become fairly routine in the United States. In Europe, however, crane manufacturers and port operators have instead shown a preference for analog controls. This preference largely owes to misconceptions that abound concerning the supposed complexity of digital drives. But with the developments in crane control technology that are occurring at so rapid a pace being almost entirely in the digital area, this preference may change. The author enumerates the advantages of digital controls and explains how digital drives excel at diagnostics and provide monitoring windows into the electrical system of a crane. Crane management systems also provide data on utilization time and container handling rates.
