Bored Rotary Drilling Rig

Bored rotary drilling rig is used in bored piling. It consists of piling rig, concrete injection-molding system and power head, and long spiral drilling stem. Its inclined strut adjustment, pile frame revolution and movement functions are all controlled by hydraulic system. The cymbiform track walking-type movement mode enables flexible slew and convenient location. Bored rotary drilling rig can conduct long spiral drilling, which has a better pile-sinking performance than hammer piling, and has a lower damage chance than vibratory hammer.
