 Rotary Drilling Rigs PCL Controller   For Drill Hole Rotary Drilling Rigs

 TR Series rotary drilling rigs are designed with latest advanced technology composed of advantages based on Caterpillar undercarriage, which are the most versatile and used for deep foundation drilling,   such as construction of railway, highway, bridge and skyscraper. Max depths of piling can reach more than 110m and Max Dia. can reach 3.5 mThe rotary drilling rigs can be specially equipped with telescopic friction & interlocking Kelly bar, and casing oscillator for suiting the following applications: Cased bore piles with casing driven adapter through rotary head or optionally by casing oscillator powered by the base carrier itself; Deep bored piles stabilized by drilling fluid or dry hole; Soil Displacement Piling System
