What Are Synchronous Lifting Systems?

Synchronous Lifting Systems from Enerpac utilize multiple hydraulic cylinders—controlled simultaneously from a central PLC (programmable logic controller)—to ensure every lifting point operates in unison. Sensors and digital controls continuously monitor displacement, pressure, and load, allowing precise corrections as lifting progresses.

This level of synchronization is essential for lifting large or unbalanced loads, such as bridges, ships, turbines, and heavy industrial equipment, where an uneven lift could cause significant structural damage or endanger personnel.

How the System Works

Enerpac’s system typically includes:

• Hydraulic Cylinders placed at multiple lifting points.

• Hydraulic Power Units (HPUs) to provide pressurized fluid to the cylinders.

• Displacement Sensors to monitor movement in real time.

• Load Cells to monitor forces at each lift point.

• A Central Synchronous Controller (with user-friendly interface) to coordinate and manage lifting activity.

This closed-loop system ensures cylinder stroke and pressure are balanced with extreme accuracy—often within 1 mm—regardless of load weight distribution.

Key Features and Benefits

1. Precision Control

Enerpac Synchronous Lifting Systems allow lifting and lowering operations with sub-millimeter accuracy. This is critical for projects requiring high tolerances, such as bridge construction, heavy machinery installation, or power plant maintenance.

2. Real-Time Monitoring

Operators have full visibility over each lifting point thanks to built-in data feedback systems. Displacement, pressure, and load data are displayed on a central touchscreen or computer interface.

3. Automated Adjustments

If the system detects an imbalance during lifting, it automatically adjusts the flow of hydraulic fluid to keep all cylinders in sync.

4. Improved Safety

By eliminating manual intervention and uneven load lifting, these systems dramatically reduce risk. Personnel can conduct operations from a safe distance, and the system’s emergency stop functions offer additional protection.

5. Flexible Configurations

Available in 4, 8, 12, or more lifting points, Enerpac systems are modular and can be adapted to fit the scale and complexity of your project.

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.
