This hydraulic tool, with its compact dimensions and low weight, provides a maximum of performance and versatility in application. It has been designed for bolting applications in confined spaces. The working principle of the KXU guarantees reliable function and very easy handling. The outer part of the driver performs a swivelling motion around the centre of the ratchet. Through the fitted ratchet head, a rotary movement is then transmitted to the hexagonal head of the bolt. Support is provided by the internal section of the driver.
