Hydraulic Casing Oscillators

Hydraulic casing oscillators are used to drive and to extract large steel casings with diameters ranging from 800 to 2500 mm up to depths of 70 m. The required hydraulic power is supplied either by the excavating machine (hydraulic crawler crane or drilling rig) or by a separate power pack.
