Enerpac EVO-Series – multifunctional synchronous lifting system
Enerpac has set the control standard with the new generation of their multifunctional synchronous lifting system: the EVO-Series – the evolutionary result of more than 25 years experience in specialised hydraulic engineering and lifting technology using digitally controlled hydraulics.
This experience is available to all our customers who need assistance with critical lifting applications. By combining the incredible strength of high-pressure hydraulics with the high-speed of today's PLC-controlled systems, Enerpac has the expertise to accurately and safely lift the largest and unique structures on Earth.
The new Enerpac EVO-System is a versatile synchronous lifting system with specialized multi-functional lifting control software. One PLC-controlled hydraulic power unit can be used for 9 hydraulic movement functions. The integrated 9 inch touch screen (HMI) offers a user friendly interface with logical visual system management and navigation. The hydraulic movements and cylinder positions can be monitored and controlled during the lifting procedure with visual real-time on screen representation. The EVO-System includes active and passive system securities with five warning and thirteen stop alarms.
Enerpac synchronous lifting technology monitors & manages lifting, lowering, weighing, alignment and load transfer procedures of non-uniform distributed heavy loads. By monitoring the position and load of each lifting position, comparing it with a global datum and adjusting to the desired target position – movements are safely and efficiently managed, within permissible load and synchronous stroke tolerance parameters, preset to suit the project.
A single operator controls all movements from a central control position, which comprehensively displays the live operation and records stroke and load data for each lifting position at user defined intervals, for client scrutiny or procedure certification. The EVO-Series hydraulic power unit (HPU) is designed as a single unit for 4, 8 or 12 lifting points and can be extended into a network with up to four units. When using 2 or more HPU’s the networked system is controlled by a separate and portable master control box.
The standard EVO-System allows customers to use their existing standard Enerpac cylinders. For more complex and demanding applications the special EVO-System, the EVO-W, offers additional control features for weighing systems with or without load cells.
EVO-System features and benefits:
• Multi-functional system with 9 standard hydraulic control modes: Manual, pre-load, automatic (by position or load), retract fast, depressurize, tilting, stage lifting (step-by-step), weighing and centre of gravity (CoG).
• Available to control 4, 8 or 12 points with one HPU.
• Network capability to link up to 4 hydraulic power units (HPU) to a master control.
• Interface with easy navigation and access to set-up, movement and software menus.
• Data storage and recording capabilities at user defined intervals.
• Wireless remote control.
• Variable frequency drive motor (VDFM) and Siemens PLC for very precise synchronization and control of oil flow and cylinder stroke and speed.
• For use with standard single- or double-acting 700 bar cylinders.
• 3,0 kW hydraulic power unit with 250 litres reservoir.
The advantages of digitally controlled lifting over manual control:
Safety – PLC-controlled system eliminates manual intervention with multi-operator manual control approach. The EVO-System includes warnings, alarms and stop functions.
Full monitoring and control – Programmable failsafe monitoring and safety alarms. Reduces risk of structural damage by bending, twisting or tilting due to uneven weight distribution or load-shifts between lifting points. Easy-to-use and very user friendly touch screen interface displays the movement process, cylinder positions and load read-outs by lifting points and total load.
Increased productivity – Less staffing required than for manually controlled lifting. One operator controls the entire lifting process while the status of every lifting point is constantly monitored and displayed. Time saving is another advantage of synchronous lifting. The process does not have to be stopped after any incremental value, checked, manually re-measured and corrected. The EVO-System carries out these actions during the entire lifting process, even with low lifting or lowering speeds. Depending on the application, time savings up to 60 percent can be achieved.
Monitoring and data storage – The EVO-System constantly monitors pressure and position of every lifting point for safe and accurate control of hydraulic movements. All values can be stored on a USB-stick for later use and full documentation of the process. With satisfactory progression of the procedure the EVO-System provides both contractor and client with a clear indication that excessively high stresses have not occurred.
Networking – One HPU for single use controls 4, 8 or 12 lifting points. Networked up to 4 HPU’s must be controlled by the separate portable master control box.
