Introduction

---

This suspension mast provides a long feed stroke for using 6m long rotary percussive casing or drill rod. Due to the light weight of the mast, the crane boom can lift the suspension mast to remote position quickly, thus eliminate the need of building a large scale scaffolding platform for the drill rig to access to the drilling position, increasing productivity as well as saving the setup cost.

The hydraulic drifter can also be replaced by a rotator for DTH drilling, up to dia. 457mm.
