Koller - Model 220 kN -Hydro Vice for Short-Term Clamping of Downhole Tools

The hydraulic vice have been designed for short-term clamping of downhole tools or other cylindrical workpieces. The 3-point clamping is carried out via a manual spindle and a hydraulically operated prism. The spindle is turned down to the diameter of the workpiece. Then the required clamping force is generated by the hydraulic lifting of the prism. The prism is equipped with specially textured jaws that effectively prevent the workpiece from rotating.
