─ Switch off the mains switch. Secure the switch to ensure it cannot be turned back on accidentally.
─ Unplug the mains disconnector plug from the socket on the crane panel. Secure the socket with a padlock to ensure it is not plugged back in accidentally.
─ 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 switches to ensure they cannot be turned back on accidentally. 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 specifically to ABURemote:
─ Voltages of up to 400 V can occur in the receiver housing. An electric shock can therefore occur. Do not open the receiver housing when it is under live voltage.
─ If the transmitter is left unattended in the hall during maintenance work, the crane could be accidentally operated with it. Take the transmitter with you onto the lifting platform. Switch off the mains switch, if possible. Press the stop button.
