Three new heavy-duty robots make all hard, dull and continuous operations. Successful experience of using these robots KR 1000, manufactured by Kuka Nordics company, for manipulations with rings having weight 50–400 kg in the unfavourable conditions of cyclic work, high temperature (1200 ºC) and high humidity is described.
