TR280 Rotary Drilling Rigs are designed with latest advanced technology composed of advantages based on DOOSANr undercarriage, which are the most versatile and used for deep foundation drilling, such as construction of railway, highway, bridge and skyscraper.
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:
- High stability and quality original caterpillar base
- Compact powerful rotary head
- Emergency mode of operation for engine
- PCL controller for all electrically actuated functions, colorful LCD display
- Mast support unit
- Original Patented driving structure of double motors and double reduces
- Controlled free-fall main and auxiliary winch
- Innovative enhanced electro-hydraulic proportional system
- Ease of transport and quickly assembly
