KR2800T – BUCKET WHEEL EXCAVATOR (KK 550) - NOEN, a.s.
General description
The KK 1300 bucket wheel excavator was put into operation in 2011 in the locality of Severočeské doly – Doly Bílina. It is intended for overburden mining under very difficult mining conditions characterized by a specific digging resistance reaching the value of 200 kN/m. The excavator operates in cooperation with 1,800 or 2,000 mm wide long-distance belt conveyors. Minimum attendance of the excavator consists of an excavator operator and a connecting bridge operator.
