TEI manufactures a lightweight drill attachment specifically designed for 3 to 8 ton mini excavators. This advanced drilling platform incorporates many of the same unique and rugged features found on our larger excavator attachment. The TEI Mini Excavator Drill Attachment provides the power required for typical rock drilling applications and is ideal for installing rock bolts, soil nails and micropiles in residential and limited access areas.
As with all our drilling platform the Mini uses only TEI drifters and rotary heads. Our unique hydraulic drifters are driven by a patented internal Automatic Stroke Adjustment (ASA) system that only allows full percussion power when the drill string is engaged. Or choose from TEI’s full line of field proven rotary heads for all the power you require.
This drilling attachment is also fitted with an innovative swivel that can pass air, water and grout to accommodate the installation of hollow bar soil nails. Our standard mini excavator drill has one 360-degree positioner and a single hydraulic clamp on the drill feed. This configuration assures the TEI Mini Excavator Drill Attachment will perform well in most drilling applications.
Positioning capabilities can be increased with the addition of a second 360-degree swivel. This additional positioner allows the drill feed (mast) to rotate from the left to the right side of the excavator boom making the installation of tiebacks in a corner or micropiles in hard to reach areas possible.
