Project introduction: The industry's first laser + satellite dual system is installed on the grader, sharing a flat plate, and the system can be freely switched on the flat plate according to the different construction sites. In a large area of the outdoors, you can use the satellite system to achieve centimeterlevel flattening, and you can also freely switch between 2D and 3D systems according to your needs, whether it is leveling or curved surface construction, you can cope with it freely. In indoor or satelliteoccluded venues, laser systems can be used to achieve more accurate millimeter-level flattening.
