· High stability: equipped with new chassis designed for rotary drilling rig and adopt gravity optimization technology to double the machine stability.
· Strong drilling ability: The max. drilling depth is 24m (CFA)/56m (Kelly) and the max. pull force is 640kN which break the record and take the leading position in the international market.
· High efficiency: the originated self-crowding device (CFA) can provide 50kN self-crowding force, which improves the working efficiency when drilling in hard soil and loose pebble layers.
· New multi ratio rotary drive (CFA): adopt multi ratio rotary drive which can increase the lifting force greatly and ensures it is large enough when drilling large hole.
