ZDG450 is a kind of equipments for groove-shaping to meet moderately or very demanding piling requirements. It uses mature undercarriage technology with Zoomlion's consistent excellence, such as real-time verticality adjustment, bucket's free swing and oil hose burst proof, etc. With optional Zollern winches with free-fall function, it realizes drilling to hard soil through great free-fall impulse force and easily tackles the piling barriers brought with the hard soil, it realizes drilling to hard soil through great free-fall impulse force and easily tackles the piling barriers brought with the hard soil. ZDG450's grooving width ranges from 400mm to 1500mm and its grooving m depth gets 70m. It's the best equipment choice for meeting moderately or very demanding piling requirements.
