What Are High Tonnage Hydraulic Cylinders?

High tonnage hydraulic cylinders are heavy-duty lifting devices capable of exerting force upwards of 50 tons to well over 1,000 tons. Enerpac’s line of high-tonnage models features single-acting and double-acting configurations, offering options for both pushing and controlled retraction.

These cylinders are typically made of alloy steel or heat-treated aluminum, built to withstand rugged job site conditions. Many models come with lock nut features for sustained load-holding and replaceable bearings for extended service life.

Common Applications in the USA

Enerpac high tonnage cylinders are used in applications where massive loads must be lifted, aligned, or held with absolute control:

• Bridge construction and lifting

• Wind turbine installation

• Offshore oil platform maintenance

• Heavy machinery assembly

• Ship block positioning

• Mining equipment lifting

• Steel mill maintenance

They are often deployed in synchronous lifting systems for precision control over multiple lifting points, helping prevent tilt, shift, or collapse of structures during elevation.

Accessories and System Components

To perform at their best, Enerpac High Tonnage Cylinders are integrated into full hydraulic systems. Typical accessories include:

• Electric or air-driven hydraulic pumps

• High-pressure hoses and couplers

• Manifolds for multi-cylinder control

• Locking collars for secure load-holding

• Saddles and base plates to protect cylinder components

• Pressure gauges and valves for fine control

These systems are customizable, allowing contractors to build setups tailored to their specific lifting applications.
