Power shovels are the main stripping and mining machines. At present, NKMZ produces full-revolving crawler-mounted stropping and opencast mining power shovels with the rope-driven lifting mechanism and bucket capacity from 5 to 35 m3. These shovels are designed to mine rocks with the volume weight in the pillar being no more than 2800 kg/m3 and provide damping of the material both on trucks and to the spoil bank. |
