armored-face conveyor power in the dark

This is a place where most people would rather not go, unless they really had to. We are visiting a mine, hundreds of meters below the surface. It is hot, sticky and the artificial light is diffused by the coal dust. Our ears are booming with the noise of the machines. Down here, coal is extract- ed. Mighty armored-face conveyors tear through the coal seam. The motors never sleep; standstill means loss of earnings. All sections of the conveyor and the drive have to work reliably despite the extreme conditions.

Another conveyor has just started and the shearer with its many chisels begins to rip coal from the longwall, accompa- nied by thunderous noise. Lumps of all sizes incessantly crash on the conveyor, which moves the “harvest” away from the seam. Again and again, chunks of coal get dumped on the chain, but the plant never blocks. Yet blockages can occur, for ex- ample if the conveyor is overloaded. In such a case, the plant stops and then restarts. This calls for enormous and precisely dosed torques to ensure that the chains are not overstrained. The Voith CPC 1 600 coupling limits and safely transmits maximum allow- able torques from motor to drive system.

Lots of underground work: An armored-face conveyor tears coal off the seam – relentlessly.

Mass separation The mass inertia of the high-voltage motor does not affect the transmission side. Rapidly occurring blockages and jolts are dampened more ef- fectively than with rigidly coupled motors.

Motor start-up The multi-motor drives run-up consecutively while the coupling is empty. As a result, robust squirrel- cage motors can be used without having to overdimension the grid for starting current.

mobility in india’s capital Making Way for public transport India’s metropolis grows and grows – and so does the traffic. In their search for possible solutions, the city leaders focus more and more on public transport. Anybody who has spent a day in the streets of Delhi longs for the modern, fast and, most of all, reliable metro.

The Voith Aquatarder SWR in the drive system

The Voith Aquatarder SWR is a so-called Cooling agent secondary water retarder. It is installed at the transmission and integrated into the cooling circuit (see graph). The SWR uses the cooling agent of the engine as operating medium and is lighter than an the oil retarder. In the new Mercedes- Engine Trans- Benz Actros, 35 kilograms are thus mission saved. During braking, the Aquatarder supports the water pump of the engine. SWR Heat generated in this process can be util- ized for heating and keeps the engine at an optimum operating temperature during

coasting, making sure that CO2 emis- sions are kept within prescribed limits.
