Safety with profile overload indicator
For steel profile systems with rated capacities of 630 kg or more, a patented profile overload indicator is included as a standard safety feature when an external guide wheel (EGW) trolley is not used. In the event of overloading, the indicator physically marks the profile, leaving a visible and permanent scratch. This provides a clear warning of misuse, helping to prevent damage and ensure the crane's long-term safe operation.
