This is a small-sized unit, with the pulling capacity of 50 tons, for construction of average-diameter pipelines in urban environment

Hydraulic trenchless piercing unit with full steering capability and a pulling force of 125 tons. MNB-125 is capable of installing pipes as large as 500 mm in diameter at the distances of up to 150 m. MNB-125 is also used for trenchless replacement of old pipelines up to 600 mm in diameter by means of static pipe bursting.

A unique auxiliary system for construction of new pipelines and replacement of old pipelines by new ones, followed by installation of reinforced concrete rings.

A lightweight & portable hydraulic underground piercing unit. UNB-20 has a full steering capability thanks to radiolocation navigation system. UNB-20 is a multifunctional unit designed for drilling in areas with limited accessibility and in confined urban spaces. The works are accomplished in two steps: 1) drilling a pilot bore with directional guidance, 2) pulling a reamer and expanding the hole by means of dry compaction. After that a new pipe is pulled into the expanded hole.

This is a small-sized directional drilling unit for quick construction of pipelines, with the pulling capacity of 40 tons. UNB-40 is a heavier and more powerful version of UNB-20. It is a pit-launched machine based on the principle of dry compaction. Increased pushing and pulling force allows installing new pipes as large as 315 mm in diameter at the distances of up to 120 m. Pipe-bursting capabilities are also increased to 315 mm.

This is a mini-unit, with the pulling capacity of 48 tons, applying the trenchless technology for replacement of average-diameter pipelines. The main purpose of this innovative device is trenchless replacement of cast iron, ductile iron, concrete, ceramic and other pipes by means of static pipe bursting. It is possible to keep the same diameter as the old pipe or to increase it by some amount, depending on the soil conditions. One of the advantages of ST-40 is its compact size, allowing it to be operated in extremely confined spaces, such as Ø1000 mm wells. High degree of automation reduces the crew number and increases the safety level at the construction site: in particular

Our newest drilling rig for precision drilling with laser guidance. Small size of the rig creates new possibilities of application. The new MNBL-70 machine is integrable with our OR-1.5 modular shoring system.

MNBS-600 / Auger drilling machine with laser guidance system is designed for precision horizontal drilling and installation of gravity-flow pipelines. Laser guidance system ensures the capability to accurately control the direction and the slope of the bore path. MNBS-600 drilling rig has its own shoring system for depths up to 5 m.
