New construction of excavator for Nochten open-cast mine, Germany
Client: Magdeburger Förderanlagen und Baumaschinen GmbH
We booked an order from FAM (Förderanlagen
Magdeburg) to perform mobile milling work on a new excavator for the
coal storage area of Nochten open-cast mine.
What’s special about this order is the diameter to be
drilled for the ball bearing slewing gear as well as the ring gear for
the slewing movement of the excavator.
The diameter of the bearing surface of the
slewing gear is 8,258 mm / 8,742 mm, and the diameter of the contact
surface for the ring gear is 10,280 mm.
We completely overhauled an old drilling machine,
extended the arm and converted it from turning to milling operation
especially for this project. We upgraded the old drive system using
modern AC motors with appropriate variable frequency drives.
That enables much more flexible control.
