Hydraulic Bolt Tensioner
Development of machines for working with large fasteners
The operator for one installation at the same time is able to tighten a minimum of 20% of the flange connection. Hydroelectric station can build up pressure up to 640 bar. This is enough for example for tightening bolts with a diameter of 140 mm.
- Motor power - 0.75 kW;
- The number of revolutions of the electric motor - 1400 rpm;
- Working pressure - 69 MPa;
- Operating voltage 380 V (50Hz).
- High efficiency;
- There is no friction when tightening;
- High quality tightening;
- Does not cause twisting of long bolts, studs.
The hydraulic station can be used not only to tighten the fasteners, but also in any device for which you need to apply a large force.
