Abstract: A method for joining components using tensioning bolts, wherein the pressure is linearly increased over time when the tension bolt is hydraulically tensioned by means of a tensioning device. When a target value (Pmax) is reached, the volume is blocked so that no more hydraulic oil is supplied. The pressure decreases when the components show a setting behaviour during a holding time (tH). Pumping is resumed when a lower threshold value (PI) is reached, resulting in a pressure increase up to the target value (Pmax).

Abstract: A hydraulic aggregate for supplying a hydraulic cylinder in consecutive load strokes is monitored for its working load in order to determine the condition of the aggregate automatically. For this purpose, the time integral of the pressure is determined for each load stroke. The pressure and duration are processed into a characteristic number which indicates the wear. This makes it possible to diagnose the condition of the hydraulic aggregate at any time.

Abstract: A hydraulic aggregate comprises a container, a reservoir for hydraulic oil, and a pump driven by a motor arranged in the reservoir. The motor is a pneumatic motor.
