The nine machines will be carrying out site investigation for some of the country's upcoming major infrastructure projects. This exceeds a previous order of seven Dando Terrier rigs supplied to the Turkish railway network for ballast sampling on the country's railway lines.

Supplied with interchangeable percussion and rotary masts, the versatile geotechnical rigs are capable of a wide range of sampling methods in areas of restricted space and difficult access with little disturbance to the surroundings. Mounted on a small crawler unit, the Terrier rig features a mast assembly can be detached for remote operation, while the hydraulic tilting undercarriage allows operation on inclined slopes of up to 30 degrees from horizontal.
