Casagrande T14EP Rotary Head

Specification

The Casagrande T14EP Rotary Head is a compact and powerful small to medium sized multipurpose drilling rig rotary head. Capable of drilling using the following techniques.

Conventional top flush water/slurry/air
DTH
Top Hammer (Percussive)
Jet Grouting

The series of rotary heads do not have mechanical gear ratios and do not use series / parallel hydraulic switching for gears. The T14EP relies on Rexroth Axial Piston Motors controlled by proportional solenoids for an infinite number of gears/speeds/torque settings within a maximum and minimum range.
