Hydraulic rotating torque wrench JBRH-/JBRHW Screw technology for Hydraulic rotating torque wrench JBRH-/JBRHW wind power industry

Hydraulic rotating torque wrench JBRH-/JBRHW Juwel Schraubtechnik GmbH has developed a new hydraulic torque wrench which compared to the common and conventional hydraulic ratched systems of hydraulic torque wrenches performs the required and preset torsion moment by a permanent rotating process onto the bolt. Method of operation: A special JUWEL hydraulic pump with maximum 110 bar output pressure has to be connected via flexible twin hose to the JBRH-tool. The required final torsion moment of the tool has to be pre-adjusted at the pump by regulating the pressure according to the torque table,...
