Bucket chain excavator, Vattenfall
Guarantees reliable operation thanks to rugged threephase motors backed by high-performance automation systems. Our drive controllers minimize wear and tear, increasing the life of mechanical components. A belt speed controller system ensures that the belts are always optimally loaded, providing energy savings of up to 20% depending on the load.
In November 1997, 25 years after production commenced at Nochten opencast mine, a new conveying system, a new train loading facility, and the first stage of a coal handling area began operation. The new conveyor system is only slightly longer than the old one, but cuts rail transportation distances by 16.5 km. This means that the newly erected part of Boxberg power station can be supplied with coal directly by belt conveyor. The investment funds were released in May 1996, and a contract for the work was awarded to Siemens (as prime contractor) in November 1996. With regard to the construction of the facility a maintenance contract was entered into with Siemens. The work had to be completed in an extremely short period of time.
