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.

Industries That Use High Tonnage Cylinders

Enerpac High Tonnage Cylinders are prevalent across U.S. industries such as:

• Infrastructure & Civil Engineering – For bridge moves, rail realignment, and foundation lifting

• Energy Sector – Used in nuclear, wind, and hydroelectric power installations

• Shipbuilding & Maritime – Lifting heavy hull sections and drive assemblies

• Aerospace & Defense – Supporting large-scale component testing and placement

Simplex hydraulic jacks and cylinders are widely used across various industries due to their robust design, reliability, and high lifting capacities. Whether for light-duty applications or ultra-heavy lifting projects, Simplex offers a diverse range of hydraulic equipment suited to different operational needs. In this guide, we will explore the tonnage capacities of these jacks and cylinders, their common applications, and the hydraulic pump pressure required to operate them efficiently.

Tonnage Capacities of Simplex Hydraulic Jacks and Cylinders

Simplex manufactures hydraulic cylinders and jacks in a wide range of lifting capacities:

• 1 to 5 Tons: Ideal for light-duty tasks such as automotive repairs, small equipment maintenance, and general industrial use.
• 5 to 20 Tons: Commonly used in manufacturing, heavy equipment servicing, and construction applications.
• 20 to 50 Tons: Frequently employed in heavy-duty industrial lifting, bridge construction, and infrastructure projects.
• 50 to 100 Tons: Utilized in large-scale construction, railway maintenance, and shipbuilding.
• 100 to 150+ Tons: Designed for ultra-heavy lifting applications, including mining, structural lifting, and major infrastructure projects.

Some of the most powerful Simplex cylinders, such as the R10010 model, can lift 100 tons, while other models exceed 150 tons, making them suitable for highly demanding lifting operations.

Common Tonnage Requirements and Industrial Applications

While Simplex offers a broad range of tonnage capacities, the 5 to 20-ton range is among the most commonly used due to its balance between power and portability. The 100-ton and higher models are reserved for specialized heavy lifting needs.

Industries that commonly use Simplex hydraulic jacks and cylinders include:

• Manufacturing: Used for heavy machinery maintenance, press operations, and assembly line support.
• Construction: Essential for lifting steel beams, foundation work, and bridge support.
• Automotive & Transportation: Employed for vehicle lifting, railway maintenance, and aerospace engineering.
• Oil & Gas: Critical for positioning and maintaining heavy drilling equipment.
• Mining & Infrastructure: Used in underground mining operations and large-scale infrastructure projects.

Hydraulic Pump Pressure Requirements

To operate these hydraulic jacks and cylinders efficiently, the correct hydraulic pump pressure is essential. Most Simplex hydraulic jacks and cylinders require 10,000 PSI to function properly. This standard pressure allows for compatibility with various hydraulic pumps and ensures consistent performance across different tonnage capacities.

For higher-tonnage applications, larger pumps with greater flow rates may be needed to achieve optimal lifting speed and efficiency. It’s crucial to pair the correct hydraulic pump with the cylinder capacity to ensure safety and performance.
