Độ chính xác cao trong việc tạo lỗ rỗng với giàn khoan quay SUNWARD SWDM300.

High torque and strong penetration into rocks, compatible with complex geological formations

The rated output torque is 300kN · m (the upgraded 300H model can reach 320kN · m), with a maximum pressure of 260kN, matched with a Cummins 298kW high-power engine. The drilling efficiency of moderately weathered limestone, granite, and hard interlayers is more than 20% higher than that of similar models, making it the main model for large-diameter deep piles and rock socketed piles.
The maximum borehole diameter is 2.5m and the deepest borehole is 90m, suitable for high-rise buildings, large bridges, wind power foundations, and heavy pile foundation projects in ports.

Patent enhanced power head with longer lifespan and lower failure rate

Equipped with invention patents to strengthen the driving key bar, eliminating the problem of bolt breakage in traditional model key bars, and extending the service life of supporting drill rods by 10%; Built in multi-point forced circulation lubrication+multi-layer sediment seal, high-strength continuous heat dissipation into the rock, the gearbox is not easily damaged by mud, greatly reducing the frequency of construction site shutdown and maintenance.

High flow hydraulic system, fast pile forming speed

Load sensing+total power adaptive hydraulic matching, main winch lifting speed up to 80m/min, single-layer large-diameter drum winding, steel wire rope life increased by 60%; The actions of lifting soil, drilling, and throwing soil are coherent, and the daily pile formation rate under the same rock embedding conditions is higher than that of competitors. It has been measured that an additional 1-2 pile foundations can be completed per day under the same rock embedding conditions.
