Hydraulic cylinder | Single acting | Hollow piston

The HHS series Single acting hollow cylinder pistons - the powerful solution for pulling and lifting applications!

The HHS series has been carefully designed with a Hollow piston, allowing a rod or cable to be fed through the entire cylinder length. This makes it perfect for situations where reliable pulling power is required. Whether for post-tensioning, prestressing or testing various anchoring systems, the HHS cylinders deliver performance that can be relied upon.

With capacities ranging from 11 to 61 tonnes and stroke lengths between 25 and 152 mm, our cylinders offer impressive versatility to meet specific needs. With a working pressure of 700 bar, these cylinders can be relied upon to deliver the power needed to keep various projects running smoothly and efficiently.

At HHS, we go for nothing less than excellence. That is why our plunger rods feature nitrocarburisation, ensuring a durable and robust construction. Low-friction bearing surfaces ensure smooth operation and reduce wear, extending the life of the cylinder.

Our cylinders feature anti-extrusion seals to prevent leakage and ensure reliable performance even under demanding conditions. For added versatility, optional piston rod saddles can be added to meet certain unique project requirements.

Safety is our top priority, which is why our cylinders come with collar thread protection as standard. This provides an extra layer of protection and extends the life of the cylinder, even in the most demanding environments.

Whether for re-tensioning, pre-tensioning, general lifting applications or other applications requiring reliable pulling power, rely on the HHS series Single acting hollow cylinder plungers. With our excellent capabilities and high-quality construction, we deliver the power needed to make projects a success.
