HDI uses Rack & Pinions drilling machines. They are based on a model created by the company in 1984, which has now become the industry standard.
HDI’s drilling rigs offer a pulling capacity ranging between 35 and 400 tons. They allow for the installation of small size pipelines over short distances as well as large diameter pipelines (up to DN 1400) over very long distances.
Rigs are trailer or crawler mounted and consist of a central beam rack with a carriage moved by pinions powered by hydraulic motors. Hydraulic rotary motors located on the carriage provide the necessary rotary force.
Each drilling rig has its own control cabin, steering kit, high pressure pump and other ancillary equipment forming a complete and autonomous drilling spread.
The HD 650 and HD 350 models are designed and manufactured in-house.
