Chuck

The hydraulic chuck is a tool designed to facilitate man in the jet-grouting activity, idea, design, work, test and the mandrel is now reality.

The hydraulic mandrel is simply the result of our hard work, which depends on the requests we receive from our customers. It is a hydraulic accessory that is installed in the drilling machines and is used in jet grouting; it is designed to block, drag and – thanks to the rotating box installed on board the machine – also rotate the drilling rod. The clamping diameters are as follows: 89, 114, 127, 140 mm.
