The principle of a workstation bridge crane is to make the work of a user easier by designing the system to move freely. When power is required to the lifting equipment it is traditional that standard festoons provide this function, however not without problems.
As a standard upgrade option the MET-TRACK system has available an enclosed conductor system, named 4DUCTOR, that can be fitted to the runway and bridge if festoon loops would pose a problem. This simple to add system offers no resistance to the easy movement of a workstation crane but benefits the installation of end to end travel removing the need for festoon storage.
