Static Pile Drivers


We operate Russia’s largest pile driver fleet –
8 units of Starke YZY-320 machines


The Starke YZY-320 hydraulic pile pressing machine is a new type of silent piling machinery. Using static force to drive and pull piles prevents damages and uncontrollable microcracks in pile bodies which are inherent to the pile hammering process. During the static pile driving, the machine’s own weight transforms into the required static load on the lever principle.

The machine is able to move independently around the construction site by means of its own walking chassis. It is also equipped with a crane to handle piles into work.

Starke YZY-320 pile pressing machine’s equipment is highly effective, reliable and safe. It effectively operates in all climatic zones over the Russian Federation and regardless of any weather conditions.

Drilling Rigs


The Company’s fleet –
2 Starke ZKL-800 rotary drilling rigs


The Starke ZKL-800 electrically-powered rotary drilling rig is designed to drill pilot wells 26 metres deep (by an integral auger), install compaction piles, heavy-duty piles and bored and cast-in-situ piles using the CFA method. Installation of slant legs, turns and movement functions of the machine are controlled by the hydraulic system.
