Inspecting the conductor system

Only with conductor system as mains power supply or trolley power supply

This section is only applicable if a conductor system is used as the mains power supply or the trolley power supply.

 

Danger to persons from electric shock! There are high voltages of the conductor system. This voltage could injure or kill people. Before performing any work on the conductor system, switch off the crane and secure it against being switched back on.

 

Danger to persons due to failure of protective conductor! The protective conductor is also connected to the crane through the conductor system. If the conductor system and the current collector are not carefully inspected and maintained, it is possible that the protective conductor may be broken. Regularly check the conductor system and current collector.

 

 

   Inspect the sections of the conductor system, the joints of the sections and the suspensions. The parts should not be broken, deformed or otherwise damaged.

   Inspect the inside of the conductor system. It should not be heavily soiled (e.g. due to rubbing of the carbon strip or dirt in the surroundings).

   Inspect the sections of the conductor system. The surface of current-conducting rails must be smooth.

 

 

   If the conductor system is heavily soiled or the surface of the rails is not smooth, blow off with compressed air or clean with a cleaning trolley.

The cleaning trolley is supplied through ABUS Service. See ABUS Service.

 

 

   Check the running characteristics of the current collector. It must run smoothly and without resistance in the conductor system.

   Take the current collector out of the conductor system.

   Check the thickness of the carbon strips. The carbon strips should not show more wear than is permissible.

How much wear the carbon strips are allowed to have is either specified on the current collector (according to the conductor system) or the maximum wear is indicated by a marking on the carbon strip itself.

   Check the wheels of the current collector. They must run smoothly and be free of damage.

 

 

   If the current collector does not run smoothly or the carbon strips are more heavily worn than is allowed, replace the current collector completely, or (if possible) replace the carbon strips.
