The collector trolleys are supplied as standard with carbon brushes for 35A, positioned according to the product drawing and table.
The brushes in positions 4 and 5 are both fitted as double brushes (“twin brushes”). Twin brushes are smaller than the others and their capacity is 35A per set. Advantages of this construction are a perfect balanced collector trolley. Gliding shoes can very easily be mounted to the collector
trolley by means of a dovetale construction. Per collector trolley 4 gliding shoes are required.
There are special gliding shoes available for high-speed applications (suffix ‘../GS’).
