This is the integrated hydraulic crawler drill HCR series that proposes a new standard by including a new hydraulic drifter.
FRD has developed Dual Damper System first in the industry.
For maximum energy transfer, Active DDS minimizes return of shock waves by keeping the bit firmly against the rock at all times during drilling.
Active DDS minimizes percussion energy loss and, by optimizing the overall feed force required, produces straighter holes.
