TR220D rotary drilling rig is new designed self-erecting rig mounted on original Caterpillar 336D base,adopts advanced hydraulic loading back technology, integrates advanced electronic control technology,which makes the whole performance of TR220D rotary drilling rig reach advanced world standards.

TR220D rotary drilling rig is specially designed to suit the following applications:

1.Drilling with telescopic friction or interlocking kelly bar - standard supply;

2.Drilling cased bore piles ( casing driven by rotary head or optionally by casing oscillator);

3.CFA Piles by means of continue auger;

4.Either crowd winch system or hydraulic crowd cylinder system;

5.Displacement piles;

6.Soil -mixing


Rotary Drilling Machine Original CAT TR220D Rigs Foundation Pile Equipment

Main Features

1.Retractable original CAT 336D chassis with EFI turbocharged engine ensures the stability of the whole machine meet the performance on various applications and construction environment.
Advanced main pump adopted negative ow constant power variable automatic control, which can realize the optimal matching in the load and the output power of engine.
Width of crawler can be adjusted between 3000 and 4300mm.
Counterweight moved back wards increases the stability and reliability

2.The system circuit is using Caterpillar hydraulic system as the main control circuit and the pilot control circuit. With the advanced loading back technology, the system achieves optimum matching in negative flow constant power hydraulic pump and output power of engine.Pilot control makes the operation exible, comfortable, exact and safe. Various kinds of hydraulic elements adopted world famous brand, such as Rexroth, Parker, etc. ensure the hydraulic system high reliability.

3.Electric systems are from Pal-Fin auto-control, optimal design of electric control system improves the control accuracy and the feed back speed. Equipped advanced automatic switch of manual control and auto control, the electronic leveling device can monitor and adjust the mast automatically, and guarantee a verticality condition during operation.

4.TR220D has separated auxiliary winch collocated on the mast from triangle parts, good view and maintenance
more convenient. The main winch has highlights of touch-bottom protection, priority control and fast line speed,
which can greatly increase main winch releasing speed and decrease ineective working time.

5.Compacted Parallelogram structure reduces the length and height of the whole machine, thus reduce the
machine's requirement on the work space, easy transportation.

6.The newest designed winch drum structure is to avoid steel wire rope tangling and lengthen the service life of
steel wire rope.
