The series FA 860 of operation for mining equipment Aue (BBA) refers to a compound locomotive (battery and contact wire operation), which from 1987 to 1991 for the mining operations of Wismut was built.
development
The FA 860 is based on the B 660 . Another battery tender with a pantograph was added to the driver's cab in the direction of travel. The idea for the development of this locomotive was to use the tractive power of a contact wire locomotive on the main lines and to be able to drive on the catenary-free branch lines without switching.
Constructive features
mechanics
The three drive units had an outer frame, which was the supporting structure. The driver's cab was hung as a litter between the second and third battery tenders. It was carried out with a welded frame. The locomotive had a manual spindle brake as a parking brake. The braking force was transmitted to the drive units via a cable.
Electrics
Each of the six axes was driven by a drive motor in the cradle bearing . The three batteries as well as the two DC motors in series in a tender are connected in series. When starting up, the two motor groups are first connected in series and then in parallel via resistors. The travel and braking levels can be selected with the cam switch. In addition to a pantograph, the middle tender had a small battery of 42 V.
