WB Equipment Double Acting

Enerpac & Simplex Double Acting Cylinders offer powerful, precise hydraulic force in both extension and retraction. Unlike single-acting models, they use hydraulic pressure for both movements, ensuring faster operation and greater control. Ideal for industrial, construction, and heavy-lifting applications, these cylinders provide efficiency, durability, and high performance in demanding environments.

What Are Double Acting Hydraulic Cylinders?

Double acting hydraulic cylinders are actuators that apply hydraulic pressure to both the piston and the rod sides of the cylinder. This allows for:

  • Powered extension and retraction

  • Stronger and more controlled movement

  • Greater flexibility in orientation (vertical, horizontal, or upside down)

  • Improved performance in fast-paced or complex operations

Enerpac’s double acting cylinders are typically rated to 10,000 psi (700 bar) and come in a wide range of stroke lengths, mounting options, and tonnages—from small industrial cylinders to heavy-duty high-tonnage models.


Where and How Are They Used?

Enerpac Double Acting Cylinders are favored when hydraulic control is needed throughout the full stroke cycle. Applications include:

  • Hydraulic presses and tooling systems

  • Automated lifting and lowering machines

  • Construction hoists and bridge lifts with controlled descent

  • Rail car and transport equipment service

  • Pipe and flange separation or alignment

  • Push-pull assemblies and testing systems

In these applications, the operator has complete control over both directions of movement, making double acting cylinders ideal for precise positioning, heavy lifting with controlled lowering, and mechanical testing.


System Components and Accessories

To operate correctly, double acting cylinders require two hydraulic ports—one for extension, one for retraction—and work best with dual-control accessories:

  • Electric or air-powered pumps with 4-way valves

  • Directional control valves for fluid routing

  • Dual high-pressure hoses and quick couplers

  • Mounting hardware (flanges, base plates, clevis ends)

  • Tilt saddles and load alignment tools

  • Pressure gauges and stroke limiters for monitoring**

Many Enerpac systems include synchronized control boxes, especially for lifting large structures with multiple double acting cylinders working in tandem.


Industries in the USA That Use Double Acting Cylinders

Enerpac Double Acting Hydraulic Cylinders are used extensively across the following U.S. industries:

  • Construction & Infrastructure – For controlled lifting of bridge decks, beams, and foundation structures

  • Manufacturing & Automation – Integrated into jigs, fixtures, and assembly presses

  • Mining & Energy – For tensioning, pushing, and heavy component movement

  • Railroad & Transport – Used in jacking systems where quick retract is needed

  • Aerospace & Defense – For controlled motion in maintenance and testing stations

  • Marine & Offshore – Ideal for push-pull setups in tight spaces and ship maintenance

Their speed, control, and reliability make them essential in any application that can’t afford delays or imprecise force application.


Why Choose Enerpac Double Acting Cylinders?

Enerpac’s double acting models are designed for precision under pressure, offering clear advantages:

  • Hydraulic force applied in both directions

  • Faster operation—no waiting for spring return

  • Ideal for automation and remote-controlled systems

  • Suitable for all orientations—no gravity required for retraction

  • Engineered for high-cycle, high-force environments

From field repair to factory automation, Enerpac double acting cylinders are built for serious performance and control.


Interesting Facts

  • Enerpac’s double acting cylinders are often used in synchronized lifting systems, where multiple cylinders must move in unison within millimeters.

  • These cylinders are preferred for horizontal or upside-down lifting, where gravity return wouldn’t work.

  • When paired with solenoid valve-controlled pumps, double acting cylinders can be fully remote-operated.

What Are Simplex Pancake Lock Nut High Tonnage Hydraulic Cylinders?

Simplex Pancake Lock Nut High Tonnage Hydraulic Cylinders are specialized, low-profile lifting solutions designed for applications where space is limited, but high load capacity is required. These cylinders feature a lock nut mechanism, which provides mechanical load holding, ensuring safety and stability even under prolonged use. With their pancake design, they are built to fit into tight spaces while delivering exceptional lifting force.

Where and How Are They Used?

These cylinders are ideal for operations requiring high tonnage lifting in confined spaces. Their primary uses include:

  • Bridge and Infrastructure Projects – Used to lift, level, and support heavy structural components.
  • Heavy Equipment Maintenance – Applied in lifting large industrial machinery, mining equipment, and construction vehicles.
  • Steel and Shipbuilding Industries – Essential for positioning large steel structures and ship components.
  • Oil & Gas Sector – Used in pipeline installation, rig maintenance, and refinery operations.
  • Rail and Transportation – Utilized for track maintenance, locomotive lifting, and heavy-duty vehicle servicing.

These cylinders are typically used in conjunction with lifting systems and can be operated in synchronized groups for even load distribution across multiple points.

What Type of Pumps Are Needed?

To function effectively, Simplex Pancake Lock Nut High Tonnage Hydraulic Cylinders require high-pressure hydraulic pumps. The most commonly used pump types include:

  • Manual Hydraulic Pumps – Suitable for precise, controlled lifting in lower-tonnage applications.
  • Electric Hydraulic Pumps – Provide faster operation and are ideal for high-cycle industrial applications.
  • Air/Hydraulic Pumps – Preferred in environments where electric power sources may not be available or safe to use.

The choice of pump depends on the specific operational needs, required lifting speed, and environmental considerations.

Industries That Use These Cylinders in the USA

These hydraulic cylinders are widely used across various industries in the United States, including:

  • Construction & Infrastructure – For heavy lifting in road and bridge projects.
  • Manufacturing & Heavy Industry – Applied in factory maintenance and heavy machinery operations.
  • Oil, Gas, & Energy – Used in drilling platforms, pipeline construction, and power plant maintenance.
  • Mining & Material Handling – Essential for servicing large mining vehicles and moving massive loads.
  • Transportation & Railways – Used in railcar maintenance, track lifting, and transportation fleet servicing.

Interesting Facts About Simplex Pancake Lock Nut High Tonnage Hydraulic Cylinders

  1. Ultra-Low Profile Design – Enables lifting in spaces where standard hydraulic cylinders would not fit.
  2. Lock Nut for Load Holding – Enhances safety by mechanically securing the load without relying on hydraulic pressure alone.
  3. Corrosion-Resistant Coating – Many models feature a protective finish for harsh working conditions.
  4. High-Tonnage Capacity – Capable of lifting and holding weights of several hundred tons.
  5. Synchronous Lifting Potential – Can be used in tandem with multiple cylinders for evenly distributed lifting.
