DDM-30 is a complex of the equipment for trenchless lining of pipelines in diameter of 500 mm with a horizontal directional drilling method.
Due to the unique universal design of the machine, DDM-30 allows to drill equally effective from the ground and as well from the ditch. All that in a combination with compact design of the machine provides a wider applicability and mobility in constrained conditions.
Transportation of all this drilling complex can be carried out on light truck (manipulator) and also on a trailer.
There is no necessity to purchase an expensive additional trawl for DDM-30 as it needs for transportation of HDD machines similar class.
Unlike analogues, construction of the mud supply system makes low demands for water quality for the preparation of bentonite mud, usual water from a nearby reservoir is enough.
Thanks to the unified assemblies, the cost of equipment, accessories and consumables is low in comparison with similar production from Europe and the USA. Also as well as at the other machine tools the expense of bentonite mud is only 80 l / min at this series against 300 l / min at analogues which is 3-4 times reduces expense of costly bentonite powder.
The design, assemblies, and also the complete set of drilling tools DDM-30 are protected by patents.
