  • KR1300Xk – BUCKET WHEEL EXCAVATOR (K 400) - NOEN, a.s

    The K 400 compact bucket wheel excavator was delivered in 2015 to the Mini Marica Iztok mine in Bulgaria. This excavator is intended for mining of the former inner dump of the mine. This reason resulted in a requirement for extremely low specific pressure on ground surface for travelling: 0.065 MPa. By means of a travelling charging hopper, the
