Industry • The history of roadheaders
The R-120, R-130 and R-150 roadheaders were developed to tackle the challenge of increasing the power of the cutter head to expand the capacity to mine rocks harder than coal. Finally, noticing the development limitations of the base model, i.e. the AM-50, the KR-150 medium-weight roadheader was designed.

Buying a Roadheader?: Here's What to Consider
Roadheaders provide precision within 5 cm, whereas drill-and-blast is on the order of 30 to 35 cm. The more precise the profile is, the more savings are achieved because less shotcrete is required to fill the voids. The precision is made possible by electronic navigation using an external theodolite. A surveyor marks a set point, and …
