The EL 6 series of the LEW Hennigsdorf describes an electric locomotive that 240 copies were built from 1952 to 1985. 220 of these were built in the main plant and 20 in the VEB Inducal Göllingen branch .
development
These mine locomotives were built in different versions. 61 of the 220 locomotives in the main plant were exported. Of these, 36 locomotives were delivered to Hungary , 13 to Romania , 10 to China and 2 to Tunisia . Of the 140 locomotives remaining in the country, 71 went to copper mining, 22 to hard coal mining, 15 to salt mining and 32 to Wismut AG / SDAG Wismut . The 20 locomotives built in Göllingen received the SDAG Wismut.
Constructive features
mechanics
The frame of the locomotive was made from welded heavy plate . The frame was first supported by leaf springs and later by helical springs . The wheel sets were on roller bearings and had disk wheels. The brake was designed as a manual spindle brake with brake pads on each wheel. The locomotive has an end driver's cab and many of the locomotives have a passenger seat at the other end. The pantograph was on a portal above the frame. In addition to the pantograph, there were also versions with a pantograph.
Electrics
The EL 6 has a manually operated cam travel switch with a mechanical safety travel lock and a self-excited resistance brake with a crossed brake circuit. Each axle was driven by a drive motor in the cradle bearing . The parallel connected direct current series motors were controlled by resistors. Nine series and five parallel speed levels and nine braking levels could be selected with the drive switch. For safety reasons, the lighting was implemented using a 12 V lead-acid battery.
