The EL 14 series of VEB LEW Hennigsdorf is an electric locomotive , 16 of which were built between 1953 and 1958.
development
This mine locomotive was used exclusively in the Mansfeld and Sangerhausen copper districts. To overcome the differences in height in the mine field were surfaces with a dip again from 6-10 °. In order to be able to drive on these with locomotives, a rack railway was necessary. Two AEG locomotives were in use on the 2400 m long rack railway in Ernst-Thälmann-Schacht, which had existed since 1934. With the extension of this line by 850 m and the construction of a 6500 m long rack railway in the progress shaft, additional locomotives were needed. These were built on the basis of the two existing AEG locomotives. With the cessation of mining in Mansfeld, the locomotives were moved to a 4000 m long rack railway in Sangerhäuser Bernhard-Koenen-Schacht. In addition to the 16 locomotives built, an order was not honored in 1953. Two locomotives that were ordered in 1960 were also no longer built.
Constructive features
mechanics
The frame of the locomotive was made from welded heavy plate . The locomotive has a terminal cab. The two pantographs were on the stem. The drive takes place via a slip clutch on an intermediate shaft and gear on the wheels and the gear. Both are permanently driven. For safety reasons, the locomotive had four brake systems. In addition to the electrical resistance brake, there was also a compressed air brake, a centrifugal brake acting on the motor shaft and a parking brake acting on the drive gears.
Electrics
Each axle was driven by a drive motor in the cradle bearing . With the cam travel switch, sixteen row speed levels, ten parallel speed levels and sixteen braking levels could be selected for the direct current series motors via a resistance control. The motors required for the compressor were fed via catenary.
