Hydraulic tool

A hydraulic tool, comprising an action part arranged to act on a threaded connector for tightening and loosening the same;

• a drive part arranged to operate said action part so that said action part tightens or loosens a threaded connector, said drive part being formed as a hydraulically-operated drive and including a hydraulic cylinder-piston unit having a first axis;
• hose means arranged to supply a hydraulic working liquid to said drive;
• and a connector connecting said hose means with said drive part, said connector including a first connector portion mounted on one of said parts turnably relative to the latter about said first axis of said hydraulic cylinder-piston unit;
• and a second connector portion mounted on said first connector portion turnably about a second axis which is inclined substantially perpendicularly relative to said first axis of said hydraulic cylinder-piston unit, so that said hose means are turnable relative to said one part about said first axis of said hydraulic cylinder-piston unit and also about said second axis which is substantially perpendicular to said first axis of said hydraulic cylinder-piston unit, said hose means including two hoses each having one end connectable with a source of hydraulic working liquid and another end connected with said connector, so that the other ends of said two hoses are jointly turnable about said first axis of said hydraulic cylinder-piston unit and also about said second axis which is substantially perpendicular to said first axis.
