? It adopts imported Kawasaki hydraulic parts, featuring reasonably matched power system and high work efficiency.

? The special telescopic chassis for rotary drilling rig use ensures stability.

? The dual-housing luffing mechanism is convenient for transportation and it also improves reliability.

? It adopts Cummins engine; and the unique design of speed regulation saves fuel.

? It takes centralized lubrication system as standard configuration, which features more convenient service and maintenance.
