The series EL 61 of the operation for mining equipment Aue (BBA) indicates a Akkumulatorlokomotive , which was built from 1961 to 1977. It was mainly manufactured for the SDAG Wismut mining operations , but it was also supplied to other mining operations. Over a hundred of this locomotive were produced.
development
The EL 61 is a tandem version of the Metallist . The two battery tenders correspond to a metallist without a driver's cab. This was hung as a litter between the two battery tenders. The background for the development was to achieve an increase in performance under the same operating conditions.
Constructive features
mechanics
The two drive units had an outer frame, which was the supporting structure. The driver's cab was hung as a litter between the two 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 four axles was driven by a drive motor . The two batteries and the two DC motors in series for each 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.
