KRP-3-660 / 1140

  • KRP-3-660 / 1140

Combine KRP-3-660 / 1140 is intended for carrying out arched mine workings with a cross section of 8 m2 with an inclination angle of ± 15º in salt rocks with cutting resistance up to 450 N / mm, as well as for mining. The harvester carries out breaking of the rock mass, unloading it from the face and loading it into a vehicle installed behind the harvester.

The KRP-3-660 / 1140 combine is a continuation of the PKS-8 series of combines.
