The EL 9 series of the LEW Hennigsdorf is a battery locomotive that was built from 1952 to 1989 in 1703 copies. Of the 762 exported locomotives, 308 were sent to Poland, 201 to China, 112 to the ČSSR, 87 to Hungary, 24 to Romania, 22 to Bulgaria, 5 to Yugoslavia, 2 to Brazil and 1 to Brazil Algeria delivered.
development
These mine locomotives were built in different versions from 1948 to 1989. For the period from 1948 to August 1949 there is no evidence of the number of units built. With the serial number 6428, the EL 9 was the first new locomotive built in the LEW. From the beginning of the eighties, production was relocated to VEB Inducal Göllingen . The 77 locomotives planned for 1990 were no longer built.
Constructive features
mechanics
The locomotive has an outer frame with two pivot bearing motors . The four speed levels are selected with the aid of a high-voltage cam switch. In addition to the speed step switch, there is a travel direction switch in the driver's cab with a type of open-ended spanner (colloquially called a locomotive key) to select the travel direction and the off position. This key can only be removed in the off position (middle position) to protect the vehicle against being used by unauthorized persons. A dead man's switch is in the form of a pedal on the floor of the vehicle. This pedal must be pressed permanently and not cyclically, as with standard gauge locomotives.
Electrics
The drive accumulator consists of 2 battery sets with 36 V each (18 × 2 V cells). The 4 speed levels of the locomotive are achieved by connecting both the 2 battery sets and the 2 traction motors, depending on the speed level, by connecting them in series and in parallel .
- z. B. the batteries in parallel and the traction motors in series , so that a high current is available at half the motor voltage, in order to be able to start slowly but powerfully.
In addition, the driver's cab has an electric heater, which also serves as a series resistor to generate the 24 V from the 36 V of a drive battery to operate the route lighting and signaling device (horn).
The vehicles have mountings for the chain coupling and coupling rod and a manual sand spreader . They are braked with a mechanical spindle brake .
