The MEDIAN rig is a multipurpose machine designed for tunnel, underground, and a wide range of other engineering construction projects, especially in limited spaces due to its compact structure.
The mast of the machine can turn 360° horizontally and 120° to -20° vertically, with a height adjustment range of 2650 mm, allowing for full-angle drilling in all directions.
The rig supports a drilling diameter range of 250-110mm and can achieve a drilling depth between 50 to 150 meters.
It can be configured with a Single Diesel Engine (Deutz AG 1013C, 109KW), a Double Diesel Engine (Deutz AG 2011, 47KW), or an Electricity Motor (90KW).
The machine is easy to operate thanks to its electric controller, hydraulic crawler drive, and a wired-remote control system which makes operations safe and convenient.
Adjustable functions include the translation and rotation of the pivot, tilting angle adjustment of the mast, repositioning of the drilling hole, pull-down pressure adjustment, pull-up speed adjustment, and the rotation speed of the rotation head.
