English to Czech Tech/Engineering Engineering: Industrial Mechanical Engineering - Bolt Tensioners

Stejný manuál jako prve. Jedná se zřejmě o jakýsi píst nebo válec s pístem, který tlačí na dříve zmíněný pusher. Pár vět s kontextem:

A pre-determined hydraulic pressure is applied to the system, thus stretching the stud bolt as the ram pushes against the puller.
A puller is then fitted to the stud bolt protruding above the nut and screwed down until it seats against the tensioner ram.
The hydraulic pressure is released and the load is retained in each bolt whilst the ram automatically retracts ready for the next tightening operation.

Na tom videu bohužel ram vidět není, nebo aspoň nijak výrazně.

Díky!
