جهاز حفر دوار عالي الكفاءة BG25

German original hydraulic system with extremely low durability and failure rate

Bao’e closed-loop high-pressure hydraulic system, with original precision components for valve groups, motors, and power heads; Stable pressure output, strong resistance to impact loads, and low risk of internal leakage and wear during long-term continuous operation in hard rock and gravel layers. The overhaul cycle is much longer than that of domestic models, and the maintenance time on construction sites is extremely short.

Smooth torque output suitable for complex geological formations

Linear adjustable torque range of 245kN · m, high drilling efficiency in soft soil, clay, and quicksand layers; Moderately weathered rocks and dense pebble layers can be stably cut, taking into account both large-diameter deep piles and hard geological construction, suitable for building pile foundations, bridge pier piles, and municipal foundation pit support in all scenarios.

The mast and the whole machine have extremely strong rigidity, and the verticality accuracy of the borehole is high

Thickened overall welded mast+heavy-duty chassis counterweight, with a reasonable center of gravity design for the entire machine; Equipped with a dual axis tilt angle automatic correction system, the verticality of the mast is monitored in real time, and the inclination error of the deep pile hole is extremely small, meeting the high standard pile foundation acceptance requirements of high-rise buildings and bridges, and rarely causing problems such as deviation or collapse of the hole and rework.

Multi method compatibility, one machine for multiple uses, high cost-effectiveness

Various foundation construction techniques can be freely switched, including conventional rotary dry drilling, mud wall wet drilling, full casing follow-up drilling, CFA long spiral extrusion pile, and SMW mixing wall; Suitable for narrow urban areas, weak foundations near water, and strata prone to collapse, with a wider range of project acceptance.
