The excavation performance is as follows: for a drilling diameter of φ460mm, the maximum excavation depth is 6000mm, and for a drilling diameter of φ610mm, the maximum excavation depth is 5000mm. Please utilize this method for various pole foundation works. 【Excavation Performance】 ■ Drilling Diameter φ460mm - Maximum Excavation Depth: 6000mm ■ Drilling Diameter φ610mm - Maximum Excavation Depth: 5000mm *For more details, please download the PDF or feel free to contact us.
