Detailed Product Description

Hydraulic drilling rigs are new design with advanced technology composed of advantages based on Caterpillar undercarriage and for drilling application modules of:
- Telescopic friction and interlocking Kelly bars
- Casing drive adapter
- Casing oscillator

The specifications of TR220 piling rig have achieved international standards. The key
components are products of famous international brands with high efficiency and
reliability.TR220 equips with Caterpillar base which has proved to be powerful
and extremely reliable and the newest C-9 engine guarantees maximum performance.

It has a flexible parallelogram system that increases its agility in both working
and transport mode.

Heavy-duty Kelly bar with 440 diameter have extreme rigidity that meets the requirement of drilling into complex hard soil and rocks.

The comfortable operator's cabin is designed with total human factor consideration.
