The EL 8 series of the LEW Hennigsdorf is the name of an accumulator locomotive that was built from 1953 to 1973 in 389 copies. Of the 254 exported locomotives, 148 were delivered to Poland , 68 to China , 32 to Bulgaria , 4 to Hungary and 2 to Czechoslovakia .
development
These mine locomotives were built in different versions from 1949 to 1973. Apart from the two LEW EL 7s built , it is the largest battery locomotive made in the GDR. For the period from 1948 to August 1949 there is no evidence of the number of units built. In 1966 six EL 8/01 and 26 EL 8/02 were built. There was also a variant that was protected against firedamp for coal mining .
Constructive features
mechanics
The locomotive has an outer frame and a terminal cab as a supporting structure. The frame was welded, a manual spindle brake serves as a parking brake. In addition to the version with one end driver's cab, the locomotive was also built with two end driver's cabs. Another version has a ride instead of the second end driver's cab (see picture).
Electrics
The battery voltage is 112 V with a capacity of 455 Ah. Each axis is driven by a drive motor in the center bearing . The nine speed levels can be selected with the cam switch. The two drive motors can be connected to the accumulators in parallel or in series, which results in the basic speed steps, further intermediate speed steps can be set by means of field weakening .
