Rotary Drilling Rig KR150C

The KR150C uses a CAT chassis, and its reliability is recognized internationally. The power head has multi-stage shock absorption technology, which is not available on ordinary rigs, ensuring the stability of the whole machine construction.

The maximum output torque is 150kN.m, the maximum drilling depth can reach 52m, and the machine's drilling diameter can also reach 1300mm.The two-segment masts have also been optimized to achieve automatic butt joints and folds, improving efficiency, and helping customers to worry less.The single-cylinder luffing mechanism of this machine has stable operation and is very easy to maintain and repair. In addition, the drilling depth measurement system has been innovated, which has higher accuracy than that of ordinary rigs. The main hoist bottoming protection device (a device that will alarm if the inverted mast is close to the ground) effectively reduces the difficulty of operation and makes the machine Handy when operating machines. The keys of the power head can be used in both directions, and they can continue to be used while they are worn and the other side, which doubles their service life.Very high safety performance, in strict accordance with EU safety standards, meet dynamic and static stability requirements, and ensure safety during construction.Low emissions, environmental protection and energy saving, meet the requirements of most developing and developed countries.

KR150 in pile foundation for a complementary solar power project in Zhejiang YuYuang.

Construction conditions:Sandy soil, clay, silt, solid weathered red sandstone layer.The diameter of the drill hole is 420mm, and the depth of the hole is 7m.Operating near a river bed  with subsidence risks making it difficult for large rig to operate.Hole easily to collapse during the process.Remote location, difficult for maintenance, tight schedule.
