Enerpac’s family of EVO synchronous lifting systems provides precision control suitable for most lifting/lowering applications.

What is Synchronous Lifting?
To achieve high-precision movement of heavy objects it is necessary to control and synchronize the movements of multiple lifting points.

The PLC-control uses feedback from multiple sensors to control the lifting, lowering and positioning of any large, heavy or complex structure, regardless of weight distribution.

By varying the oil flow to each cylinder, the system maintains very accurate positional control. By eliminating manual intervention, the sync lift helps maintain structural integrity and increases the productivity and safety of the lift.

PLC-controlled synchronous lifting systems reduce the risk of bending, twisting or tilting, due to uneven weight distribution or load-shifts between the lift points.

• Managing lifting operations from a central control system improves safety and operational productivity
• Lifting system to control 4, 8 or 12 lifting points (12 points for Standard EVO only)
• Intuitive user interface provides easy set-up and control with multiple lifting options
• Accuracy of up to 1 mm between leading and lagging cylinders

The jack-up system is a custom developed multipoint lifting system. A typical system setup includes four jack-up units positioned under each corner of a load. A four unit setup has a lifting capacity of 2,000 metric tons (500 tons per unit).

The lifting frame of a jack-up unit contains four hydraulic cylinders in each corner which lift and stack steel boxes. A load is lifted in increments as boxes are slid into the system, lifted, and stacked; forming ‘lifting towers’. A jack-up system is operated and controlled by a computer control unit. Each unit’s lifting and lowering operations occur simultaneously; the computer control unit’s synchronous technology maintains the balance of the load. The hydraulics power units are embedded within each unit’s lifting frame. Safe lifting heights are dependent on the expected side load.

Four models of the jack-up system are currently available:

• JS125
  • Lifting capacity per tower: 125 tons
  • Lifting height: 6 meters
  • Maximum side load: 3% at 6 meters
• JS250
  • Lifting capacity per tower: 250 tons
  • Lifting height: 10 meters
  • Maximum side load: 3% at 10 meters
• JS500
  • Lifting capacity per tower: 500 tons
  • Lifting height: 15 meters
  • Maximum side load: 4% at 15 meters
• JS750

  • Lifting height: 20 meters
  • Maximum side load: 5% at 20 meters

Multiple jack-up units
The most common system setup includes 4 jack-up units.
Computer control unit
A touch screen control for operating the jack-up system with automatic and manual lifting settings.
Electronic controlled diesel power unit

The strand jack lifting technique originates from the concrete post tensioning principle. A strand jack can be considered a linear winch. In a strand jack, a bundle of steel cables or strands are guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved.

The motion of the cylinders is driven by hydraulic power packs. They can be electric or diesel powered. Our sophisticated SCC software program synchronizes the motion of the strand jacks and adjusts the motion to the loads per lifting point.
