The overall design of the lifting guide rail has a solid mechanism and longer service life. The height of the piling stroke can reach 5.5 meters (standard configuration: 3.5 meters). The impact force of the high-frequency hydraulic hammer of the 85mm drill rod is as high as 1400 joules. It is equipped with an angle digital display to adjust the angle quickly and is easy to drive. The reinforced structure of the shed is strong and earthquake-resistant, and the operation valve can be controlled with high precision and smoothness. When piling, the guide rail is vertically pierced on the ground to minimize the impact of vibration on the verticality of piling. The added protection of the crawler chassis is safety first.
