LEFFER hydraulic casing oscillators VRM118 and VRM150 complete the machine park, and all our drilling rigs are fitted with fixtures for these machines. Sometimes hydraulic casing oscillators are booked for emergencies and are kept in reserve at a construction site, sometimes they make large-diameter deep drillings possible. If you want to operate this equipment with biologically degradable oil, our technicians will help with the oil change, if an appropriate device is not available.
