Dredge Yard, an international producer of mining/dredging components and equipment, has just released this very interesting video about the engineering and manufacturing of their dredge ball joints.
The dredge ball joints are designed in six different types, giving variations of tilting angle from 15 to 18 degrees and duties from 10 bar to 30 bar.
All dredge ball joints are designed, produced, assembled, tested, painted, greased, packed and transported under close super vision of Dredge Yard team of engineers.
