HCG series high-capacity cylinders
High-tonnage single-acting hydraulic cylinder with gravity return - for demanding heavy lifting applications. Enerpac high-tonnage cylinders are ideally suited for multi-point lifting and applications requiring capacities up to 1000 tons and maximum operating pressure up to 700 bar (10 000 psi).
Enerpac HCG series hydraulic cylinders – high-capacity single-acting actuators (700 bar)
Enerpac HCG series hydraulic cylinders (high-capacity single-acting cylinders with gravity return, eng. Enerpac High Tonnage Single-Acting Cylinders) are specialized power hydraulics devices designed for the most demanding lifting, construction, and assembly work. The HCG series offers a capacity range from 50 up to 1000 metric tons (generating forces from 550 kN to 10 644 kN / 10,6 MN) at a maximum operating pressure of 700 bar (70 MPa). The design of these powerful cylinders is based on hydraulic advance and gravity piston return. They have been manufactured to the Summit technological standard, which means the use of hardened surfaces resistant to cyclic wear and seizure, external and internal coatings protecting against atmospheric factors, and replaceable composite bearings. Enerpac HCG cylinders are characterized by exceptional resistance to side loads reaching up to 10% of the rated value, making them an indispensable tool for lifting large-scale objects, bridge construction, shipbuilding, heavy industry, and geotechnics.
Application and technical characteristics of Enerpac HCG series cylinders
High-pressure Enerpac HCG series cylinders were created for continuous operation in extremely difficult industrial and field conditions. They are used wherever enormous lifting force, control precision, and absolute operational safety are required.
- Extreme performance and capacity up to 1000 tons: According to ASME B30.1 standards, the devices generate a resultant force of up to 10 644 kN, enabling the lifting of elements of engineering objects and structures.
- Side load resistance up to 10%: The use of double composite bearings guiding the piston protects the cylinder from jamming and damage to the cylinder bore in case of uneven weight distribution.
- Built-in Stop Ring: A durable high-hardness steel ring protects the piston from over-extension and accidental blowout from the housing under full load.
- Advanced protective coatings: The piston surfaces and the inside of the housing have undergone hardening treatment (cyaniding / nitriding), which ensures low friction and full corrosion resistance in marine and industrial conditions.
- Ergonomics and mounting versatility: Equipped with certified lifting eyes/handles, threaded holes in the base, and collar threads (standard up to 250 tons, optional E002 from 300 tons).

Frequently Asked Questions (FAQ)
What are Enerpac HCG series hydraulic cylinders used for?
HCG series cylinders are designed for heavy lifting and leveling work in heavy industry, shipbuilding, infrastructure construction ( bridges, viaducts ) and mining, where a capacity in the range of 50 to 1000 tons is required.
How does the piston return in HCG single-acting cylinders?
HCG series cylinders use gravity return. This means that after the pressure is released in the pump, the piston returns to the starting position under its own weight or the weight of the load resting on it.
How does the HCG series differ from the HCR and HCL series?
The HCG series consists of single-acting cylinders with gravity return. The HCR series consists of double-acting cylinders (with hydraulic advance and return). The HCL series is additionally equipped with a lock nut, allowing for mechanical load support for a long time.
Is it worth using CATS tilt saddles with HCG cylinders?
Yes. Optional CATS series tilt saddles allow for the safe absorption of uneven loads and permit up to 5 degrees of misalignment, which protects the piston rod from local point overloading.
