  • Pump units as the universal drive unit for stressing jacks, steelcutters etc.
  • Wire/strand pushing machines for feeding the prestressing steel into the formwork
  • Single-wire stressing jacks from 30 to 300 kN prestressing force (see table).
  • Screw jacks for the exact stressing of short prestressing wires
  • Twin ram jacks for stressing mono strands can be applied from above
  • Detensioning cylinders from 200 to 10000 kN for uniform force transmission
  • Special detensioning anchors have been developed and supplied for sliding mould production which allows the slideformer to pass over

The mini stressing jacks are suitable for short pre-stressing bed production on sizes 3 to 7 mm dia. wire/strand in the production such as fencing posts and for universities / schools for training purposes.

The mini jack is usually supplied with hand pump or mini pump unit but of course the mini jack can be used with any pump unit supplied by Paul.
