The electric mine locomotive EL 2 was manufactured at LEW Hennigsdorf from 1952 to 1988 in 1384 copies.
history
Also called "hundred-ton locomotives" mentioned, with DC -powered machines are the most-built electric locomotive - series in Germany. About half of the locomotives were delivered to GDR companies. Customers were also Bulgaria (206), China (186) and Poland (62). 245 machines of this type were delivered to the USSR between 1957 and 1970.
In Germany, in contrast to Eastern Europe and China, the original version now only exists in three copies in the Lausitz lignite mining area , where they are used in particular for de-icing overhead lines in winter. Modernized locomotives of this type run at MIBRAG (partially modernized at the Profen open-cast mine ) and at LEAG in the Lusatian lignite district, known as EL2m.
technology
The bogies are closely coupled to one another , the bridge frame does not transmit any tensile forces. Because of the close coupling, one of the pivot pins can move longitudinally. Due to the coupled bogies and the additional springs instead of compensating levers between the axles in a bogie, the machine is supported on four points. The wheelsets run in plain bearings with Peyinghaus centrifugal lubrication in the machines of the first years of construction , in the later deliveries roller bearings were installed. Typical of the mine railroad are the low-lying bumper beams instead of the railroad clearers . They are in two bogies on both sides (ie also in the vehicle center) exist and are in derailments related to particular Strossengleisen can occur more frequently, prevent slipping off the track grid. The machines delivered to German operators are usually equipped with mine train couplings. Side buffers can be built in, but not always available. A screw coupling chain can be used in the mine train coupling. This means that regular vehicles can be coupled, which is important for transporting wagon trains to the public rail network without reloading. In Poland, for example, there are also locomotives with complete screw couplings with tow hooks. The locomotives for China and the USSR were delivered with the central buffer couplings customary there.
The locomotives are equipped with pantographs for overhead lines, and side pantographs can also be installed. These are required for bench tracks and for systems in which the wagons are loaded from above. The machines were usually delivered with pantographs , especially modernized ones run with single-arm pantographs .
Because of the axle load of 25 tonnes, the locomotives are treated as exceptional consignments and heavy wagons when they are transferred in the long-distance network. Exceeding the axle load can be avoided by transporting the bridge frame separately on a flat wagon.
Museum and monument locomotives
- The locomotives 4-10-100-B3 and 4-662-100-B3 are preserved in the Lausitz mining museum, Energiefabrik Knappenrode .
