Unique Pull Down Cylinder System Building Construction Rotary Drilling Rig Diameter 1800mm and drilling depth 60m
Rotary Drilling Rigs Rated Max torque 180kN.M; Max Hole Diameter 1800mm;Max drilling depth 60m
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 m The 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.
Main Features:
1. Mounted on original Caterpillar 329D base,weight back to ensure the stability of the whole machine.
2. Adopts CAT C7 engine with ACERT TM Technology offers more engine power and runs at lower speeds for better fuel efficiency and reduced wear, more environmentally,lower noise,little vibration,optimal machine performance,more power output,less emission and makes the cost for drilling reduced.
3. PCL controller for all electrically actuated functions, colorful LCD display
4. Compacted Parallelogram structure to reduce the length and height of the whole machine,reduce the machine's request for the work space,easy for transportation.
