DR-180

This rotary drilling rig has a torque head of 180 kN.m and a drilling depth of up to 50M. Depending on the type and diameter of the drill, the drilling speed and depth will change accordingly. The remodeled rotary drilling rig is equipped with a hydraulically adjustable telescopic chassis, which can adjust the width of the chassis according to the construction environment, so that the center of gravity can be moved downward and the stability of the construction can be increased. The mast is lying horizontally when not working, and needs to be adjusted to stand up when working. When the angle between the mast and the ground is greater than 75 degrees, the automatic hammer adjustment function can be turned on, making the construction more accurate and safe. The mast also has a left-right swing function with an included angle of 5 degrees. This function is suitable for adjusting the verticality of the mast when the overall construction ground is inclined and uneven. This model has passed ISO, CE, SGS and other product quality certifications.
