Hydraulic Casing Oscillators
The hydraulic casing oscillators have been designed in accordance wiht the latest technical know-how. Extremely sturdy construction gaurantees worth-while use on site. By means of exact statical calculations in conjunction with higher quality material, an optimum conformity of loads, weight and material strength is achieved. The internal welding stresses, not easily determined for the statical calculation, and which would affect the construction considerably, are eliminated by means of stress relieving prior to machining.
