TEI can reconfigure existing rock drills for use when longer strokes are required. Our extended attachment provides the longest stroke possible while still allowing the drill to be transported while attached to the excavator. The mast offers a 25 ft (7.6 m) stroke with a 15 ft (4.6 m) rod-adder. The rod-adder has a positive grip that keeps the drill rod or auger in place regardless of the drilling angle. The TEI Extended Excavator Rock Drill can install a 40 ft (12.2 m) soil nail or micropile with only one operator.
The TEI Rock Drill Excavator Attachment is ideal for use in difficult low, high and confined environments where its 360º swivel capabilities offers an extreme range of motion. Additional drill positioning can be provided with the installation of a second 360-degree positioner that will move the drill feed from one side of the excavator boom to the other.
