The function of the single guide rail of the top drive is to provide the guide for the top drive to slide up and down, and it plays a role of righting, which is convenient for buckling when the column is connected and the casing when running the casing. The counter torque is transmitted to the derric base, and the force is not transmitted to the derric. All parts of VARCO’s top drive guide rails are made of high-quality structural steel and alloy structural steel. The connecting lugs are heat-treated, with high tensile strength and good welding performance. Its function is to complete the rotation of the drilling rig to drive the drilling tool to provide anti-torque strength. Provides a track for the top drive to move up and down during normal drilling and assembly and disassembly.
