EVO-Series, Synchronous Lifting Systems

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.

Features
   • 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 0.040 in (1 mm) between leading and lagging cylinders
   • For use with standard single- or double-acting cylinders
   • Built in warning and stop alarms for optimum safety
   • Available with several flow options for optimal lifting speed

Products
Enerpac offers two series of Synchronous Lift Systems:
   • Standard Synchronous Lift Systems (EVO): a comprehensive system for numerous applications
   • Basic Synchronous Lift Systems (EVOB): an economical solution for basic applications
   • Custom systems tailored to unique project requirements are also available.

Standard EVO Synchronous Lift System
It is a comprehensive self-contained design that features simple to use software that is extremely efficient at completing basic to complex applications.

The Standard EVO-System has nine work modes. The operator can navigate to any of these menus:
   1. Manual
   2. Pre-Load
   3. Automatic
   4. Retract Fast
   5. Depressurize
   6. Tilting
   7. Stage Lift
   8. Weighing*
   9. Center of Gravity determination*
   * Available in the EVO-W System with calibrated sensors

Features of the Standard EVO-System
   • Utilizes feedback from pressure and stroke transducers to offer both stroke control and load monitoring
   • Can be networked to link up to 4 systems together (requires separate master control box)
   • Variable frequency drive (VFD) and PLC for precise synchronization and control of oil flow
   • Data storage

Basic EVOB Synchronous Lift System
Leveraging Enerpac’s market leading Z-Class pumps and components from the standard EVO, the EVOB offers an economical solution to basic applications requiring stroke only control for a maximum of 8 lifting points.

The EVOB-System has three work modes. The operator can navigate to any of these menus:
   1. Manual
   2. Automatic
   3. Depressurize
