Drilling Products

The requirements of construction and implementation for drilling units vary a lot. The major requirements of the drilling units at bedrocks are variability and mobility on the construction site. The units are mounted on a caterpillar undercarriage. The carriage kinematics is constructed in such a way that drilling in various positions and angles is possible. These units are usually used for drilling lower depths of max. 30 m, therefore shorter drilling tools, 2 metres and shorter, are used.

Small drilling units are used for old building masonry reconstruction. They are thus optimized for drilling in confined areas (hydraulic contracting undercarriage, short carriage); the units can be transported in parts (carriage, undercarriage, generating unit).

Large drilling units can be equipped with two rotating heads. The modular design of the DSI equipment allows a flexible intermeshing of the componentes.

The drilling units for exploration work are usually mounted on wheeled undercarriages. The unit are placed over the drill hole for days or even weeks. The drill hole depths reach several hundred metres, our units reach depths of approximately 700 m. The carriage is designed for longer drilling tools of 3, 6 and 9 metres. The carriage kinematics are simple, consisting the carriage set-up and its mounting on the frame of the drilling unit only. The frame of the unit is equipped with four hydraulic outriggers for the required field set-up of the unit. The unit has only one rotating head, usually with higher rotation speed of 700 min -1 or faster, compared to the units for foundations. Casing tubes with large diameters of 324 mm or larger are used. Such large casing tubes can only be driven in with the help of a supportive casing device.

Our company also produces drilling tools. Double thread clockwise or anti-clockwise casing tubes with diameters of 133 and 152 mm are mostly designed for construction foundations. We produce drilling rods with diameters of 63, 89.9 and 114 mm. The most frequently used threads are the API 2 3/8", 3 1" IF threads, regular threads or RD threads. Other types of drilling tools are supplied from other producers.
