Description
Detailed description
Description
Strong rock penetration and deep pile capability
With a high torque of 258 kN · m and a pressure of 200 kN, it can easily handle moderately/weakly weathered rock layers, with high pore forming efficiency and stable and reliable deep pile construction.
Efficient and fuel-efficient power matching
Engine hydraulic system load global matching, increasing perforation efficiency by 10%~25%; Optimize the hydraulic system to reduce overflow losses and save fuel by 7% to 20%.
Intelligent control, precise and safe
Automatic control of mast verticality, automatic detection of drilling depth, self diagnosis of faults, precise operation, minimal misoperation, protecting the host and improving safety.
One machine with multiple functions and complete construction methods
Support multiple construction methods such as conventional bucket drills, pipe rolling machines, casing drivers, CFA long spirals, and down the hole hammers, suitable for complex formations such as clay, sand layers, pebbles, rock layers, and caves.
