Casing Rotator
Casing Rotator
In the All Casing Method (Benoto Method), the casing is inserted and drawn with the rotation of 360-degree, and it continuously excavates underground foundation structures, gravel, rocks, and hard strata. Thus, it is possible to work regardless of the geological structure and conditions. High torque and 4 thrust cylinders maintain accurate verticality and high pulling force for deep excavation with high speed.
Features
- Rotation of 360 degree drives high vertical precision and less friction.
- High Torque directly works on the top of casing shoe.
- It is user-friendly designed and further excavates without affecting nearby facilities due to low noise level and low vibration work.
- It is designed with high speed, indentation and pulling out power, and further structured with Bearing and Frame
- SAMJIN has developed Rotator (Diameter: 3,300mm) for the first time in the world and world-widely exported.
