Product Description

TR138D rotary drilling rig has adopted CAT C6. 4 engine with ACERTTM Technology offers more engine power and runs at lower for better fuel efficiency and reduced wear. turbo suction, supply 147 hp power, Optimal machine performance, more power output, less emission.

Advanced Hydraulic System & Structure

TR138D rotary drilling rig has new designing original hydraulic system. Hydraulic systems adopt Rexroth motor and valve, ensure power high efficiency when and where required. Wide crawler provides lower grounding pressure and improves the whole machine stability and adaptability. It is easy to work and transport by extendable crawler TR138D has separated auxiliary winch collocated on the mast from triangle parts, good view and maintenance more convenient, 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.
