This rotary pile driver is equipped with a high-power Cummins brand engine and a Kawasaki hydraulic transmission system to ensure that the construction power output is strong and stable. The machine is equipped with a high-capacity retractable crawler chassis, which can overcome the complicated road conditions of construction operations. The chassis telescopic function can increase the center of gravity of the pile construction and increase its stability. The pile mast has an automatic vertical adjustment function, which can be tilted 5 degrees forward and 5 degrees left and right sideways. Adjust the drilling angle for different working conditions. The rig is equipped with a new control system, which can realize steering, telescopic chassis, body rotation, mast up and down and other functions through wireless remote control. The company is a research and development manufacturing company, all models are independently designed and manufactured, and have a number of related scientific and technological intellectual property rights. Products have CE, ISO, SGS and other quality management system certifications. For more information welcome your inquiry.
