摘要： In a tensioning device for expanding a threaded bolt by a pull on its threaded end portion, a supporting tube surrounds the threaded end portion and a nut is screwed onto the threaded end portion. A cylinder is arranged in the prolongation of the supporting tube and has at least one piston movable therein in the longitudinal direction and connectable to a hydraulic supply. An interchangeable bush is screwable to the threaded end portion and is drivable axially by the piston. A gear arrangement for adjusting the nut is provided. Components of the gear arrangement are a driver element engaging externally on the nut and a drive shaft provided with an engagement structure for a drive tool. In this case, the axis of rotation of the drive shaft is arranged at an angle of preferably 90° to the longitudinal mid-axis of the piston.
