Casing Oscillators
By their sturdy and compact construction, the hydraulic casing oscillators of the BV series are designed to be used as front-end attachment to rotary drilling rigs (see pages 4 - 7). When mounted to the undercarriage of a rotary drilling rig, the full Torque of the casing oscillator can be transferred to the casing string and the weight of the drilling rig can be activated as a reaction force to the vertical forces generated during installation of the drill casing. Exact setting-up over the pile position is achieved by adjustment of the relative horizontal position between casing oscillator and drilling rig.
