Crane electrics

Premium products you can trust

There are standard contactor controls available for all common control voltages for crane systems with components from STAHL CraneSystems. In their basic version, the components are supplied with plug connections as far as this is technically possible and meets requirements. The standard equipment can be supplemented individually with various control and monitoring components as well as optional frequency inverters for hoists and travel drives to suit your specific application. This equipment will increase safety in material handling and lengthen the service life of the system.
