As a measure to protect equipment and machinery, compact hoistings must be limited at their top and bottom cutoff points. The geared cam limit switches from GKN Stromag for this reliable cut-off are ideally attached directly to the drum.
When integrated with optional, intelligent encoder technologies, these geared cam limit switches can easily determine absolute positions to a high precision.
These values can be converted into reliable additional data like e.g. sense of rotation and overspeed. Data can be transferred to the manufacturer's controller via a customer bus interface. The plant operator benefits from optimised cost control when these status parameters and appropriate preventive measures are integrated in the condition monitoring system.
