  ●The power standard for this type of drilling rig is a dual power design. The standard configuration is 76mm three-meter drill pipe or a variety of Fried Dough Twists drill pipes. It is a dual purpose diesel and electric model that can switch power at any time

  ●The large torque double cycloid motor is used to drive the rotary head, which increases the torque of the drill, up to 7000N. m, making the range of rock drilling aperture wider, which can be widely used for pit staggering, pipe following, and large diameter Fried Dough Twists drill pipe operations;

  ●The rotary dual speed switching valve is easy to operate and can meet the needs of different torque and speed operations. The 425S comes standard with a pole unloading device;

  ●Standard assembly plunger motor, international engineering machinery walking track, more powerful climbing and reliable quality.
