HFA Range

The HFA range offers the benefit of significantly reduced weight compared to conventional steel cylinders as well as combines all the versatility and efficiency of hydraulic power with the safety of mechanical load support. Ideally suited for applications requiring sustained load holding for extended periods, such as bridge support work, the HFA cylinders feature a single acting, spring assisted return piston threaded throughout its stroke length, to suit the threaded mechanical load holding lock ring. Other capacities and stroke lengths area available on request.

  • Capacities from 32 to 110 tonnes
  • Stroke lengths from 51 to 305 mm
  • Working pressure 700 bar
  • Single acting, spring assisted return
  • Hard anodised piston rod and cylinder for corrosion resistance
  • Low friction bearing surfaces
  • Anti-extrusion seals
  • Tilting saddle fitted as standard
  • Integral stop ring
