New to North America is the FRD Series hydraulic crawler top-hammer drills, replacing the HCR Series. The FRD models feature the HD-700 Series Dual Dampened drifters, which have shown a major increase in penetration rates and an increase in the service life of critical wear parts, the company says. The drills (built with Caterpillar undercarriages) have roomier, ergonomic cabs and a simplified joystick for drilling operations.
