Equipment - Diedrich D-120 High Torque/Heavy Duty Rig

Our new (2006) Diedrich D-120 rig is equipped with all the latest available features for safety, convenience, and high production drilling. In addition, this rig was custom manufactured to our specifications to make it one of the most versatile multi-function rigs in our fleet. The multiple drilling capabilities include hollow stem auger, air rotary, mud rotary, rock coring, casing advance, and continuous soil coring.

Purpose built quick change features allow field conversion between drilling methods within 30 minutes or less. Other custom options built into this rig include automatic 140 lb. sampling hammer, 650 gallon water tank, on board pressure washer and decon enclosure, hydraulic rod holder and breakout wrench, high torque rotary box with shift to high speed coring mode, high speed hoist for well development and wireline coring, and slide out rod rack which can hold 200' of drilling rod. One of the most innovative features on this unit is our automatic auger handling system which eliminates manual lifting and carrying of augers. All augers are stored in hydraulic swing out auger racks located at the rear of the rig that are positioned to allow use of the winch lines to hoist augers both in or out of the boring and storage racks.

This rig is a favorite of our clients for those projects with deep borings or difficult subsurface conditions.
