60-90 tons

Stroke

75-150mm

 

hydraulic cylinder hv series hollowSingle-acting (double-acting) hollow cylinders of the HV series are versatile for testing, maintenance, pulling and tensioning. The through hole in the cylinder allows, for example, tensioning ropes and rods, lifting suspended loads, dismantling pressed or seized machine parts such as pins, shafts, bushings, etc.

INNOVATION - Thanks to the return stroke using compressed air, these cylinders combine the advantages of single-acting and double-acting cylinders - only one hose with a simpler pump and fast return stroke even with a longer supply hose.

 

3 YEAR WARRANTY PERIOD THANKS TO PROVEN QUALITY

  • For use even in adverse conditions, the surface of the piston rod is hardened with an anti-corrosion treatment and protected by a wiper ring.
  • Standard H - hardened inner cylinder surface with increased corrosion protection leads to resistance to moisture and damage to the cylinder interior by dirt. This minimizes the possibility of seizure.
  • Standard S - high resistance to impurities in the oil thanks to the wiper ring.
  • Flexibility:
    • threaded holes in the bottom of the cylinder allow attachment to various devices,
    • For easy handling, the HV60 size is equipped with a handle as standard, and the HV90 size is equipped with a handle and hanging eyes.
  • Piston return stroke – using compressed air in the space above the piston:
    • easy to fill with air from 3 to 10 bar – like a tire,
    • large diameter of the through hole,
    • high return stroke speed,
    • smaller dimensions and weight,
    • easy conversion to a double-acting cylinder.
