Power drilling performance

280kN · m standard torque, with adjustable power head in multiple gears, supporting low-speed high torque rock entry and high-speed low torque soil layer drilling. Strong construction ability for weathered rocks, capable of handling complex formations such as 50MPa rock layers and karst caves
Double buffering and shock absorption system, five level impact resistance technology, significantly improved shock absorption performance, significantly extended service life of motors and reducers, and minimal damage to the main engine caused by drilling impact.
Smooth compound movements, synchronous operation of rotation, lifting, and pressurization, fast drilling circulation speed, and high construction efficiency

Structure and stability

High strength mast, increased stiffness by 16.7%, truss anti vibration structure, strong bending and torsion resistance, high verticality of long pile deep hole construction, good hole quality
The Sany special widened chassis has a reasonable weight distribution and excellent stability for soft and sloping operations.
High strength wear-resistant machine lock/friction drill rod, tested for fatigue under working conditions, with a long wear-resistant life for the drive key; The maximum pile diameter is 2.5m, the deepest friction rod is 84m, and the deepest machine lock rod is 54m, with a wide construction coverage.

Intelligent electronic control system

SANY-ADMS intelligent control system, high-definition touch screen, real-time visualization of drilling parameters, with drill pipe pressure table position display, effectively preventing drill pipe damage.
Self diagnosis and alarm prompts for machine malfunctions, reducing troubleshooting time; EVI remote networking, the manufacturer’s backend can monitor device operating conditions, and maintenance response is fast.
The pre tensioning function of the floating steel wire rope reduces the impact wear of the steel wire rope and extends its service life.
