The Hyundai Everdigm ECD Series of Top Hammer Drilling Rigs come with Tier 1 and Tier 3 Engines, either Cummins or Caterpillar. The ECD Series come with the Everdigm ED Series Drifters with either 16kW, 18,5kW, 21kW or 23kW versions available. Features on the ECD Range are more basic and therefore offer a lower purchase price and slightly less electronics inside the cabin. Great for those customers who just want a basic rig without all of the "frills" added over the past 10 - 15 years.
