Mining Battery Locomotive ELECTRA |
|
|
|
|
Mining, battery locomotive ELECTRA was designed in accordance with Directives 2006/42/WE and 2014/34/UE for Group I Category M2 and can operate in mining underground excavations in the conditions of existing hazards. The locomotive is intended for personnel, equipment and other loads transport. |
|
|
ELECTRA’s batteries can be charged in coal dust and methane hazardous areas, which eliminates the need of batteries reloading arrangement.The charging is implemented using mining contactor switches 500 V. The locomotive is equipped with maintenance free battery as well as in system that allows energy recovery during kinetic braking. |
|
The prototype of ELECTRA locomotive has been manufactured by “Urządzenia i Konstrukcje“ Company in Żory, thanks to the funds – among other things - from National Centre of Research and Development in cooperation with Silesian Technical University. |
