Power and Drilling Performance

Sufficient torque reserve and strong rock penetration ability: The maximum torque of the power head is 280kN · m, and the winch pressurization system has a high pressure, which can cope with hard formations such as pebbles and moderately weathered rocks. Coupled with the machine lock rod, the rock penetration efficiency is outstanding; Equipped with adaptive drilling control, it automatically matches torque, speed, and pressure to reduce gear breakage and hole deviation.
Strong pore forming ability: The maximum pile diameter of the standard model can reach 2.3-2.5m, the maximum depth of the friction rod is 83-84m, and the machine lock rod is 54-56m, suitable for large diameter deep pile foundation projects in bridges, housing construction, and municipal engineering.

structural reliability

High strength box type mast+optimized variable amplitude mechanism, high mast stiffness, anti vibration and anti deformation, added buffer structure to the power head, improved shock absorption performance, longer service life of reducer and motor, better control of drilling verticality
Large self weight and low center of gravity tracked chassis, with a total weight of about 84 tons, stable and anti overturning operation; The track has a large grounding area and good passability on muddy and soft foundation construction sites. It is available in Caterpillar chassis or Sany chassis versions.

Intelligent control and safety

Electronic Control Intelligent System: High definition touch screen, real-time display of drilling depth, torque, and mast inclination angle. Some versions come with visual monitoring of drill rods to prevent them from being damaged; 360 ° rotating platform, flexible operation direction.
Multiple safety protections: overload protection, limit protection, mast inclination protection, and anti over winding of the winch to avoid misoperation; Equipped with a centralized automatic lubrication system to reduce manual maintenance workload
