Observe the following safety instructions for any maintenance work on the crane with trolley:
─ Switch off the mains switch. Secure the switch so that it cannot be unintentionally switched back on.
─ Unplug the mains disconnector plug from the socket on the crane panel. Secure the socket with a padlock so that the mains disconnector plug is not unintentionally re-inserted.
─ Use suitable lifting platforms and fall protection equipment.
─ Adequately cordon off the operating range around the lifting platform.
─ Switch off any other cranes using the same crane track or cranes working above or below the crane undergoing maintenance. Secure the switch so that it cannot be unintentionally switched back on. Otherwise, other cranes could overturn the hoisting platform or crash into the crane undergoing maintenance.
─ Notify personnel in the area that maintenance work will be performed.
─ Only trained electricians should work on the crane electrical system!
─ Even after the emergency stop button has been pressed, life-threatening high voltages are still present in the panels.
These safety instructions apply especially to the drive:
