It is being marketed to crane clients globally and its key applications are bridge building, maintenance and other infrastructure construction.
"Basically this is a combination of all the technology we have developed and this is the next generation," says Maarten Franken, marketing director, Europe and India.
It’s useful in infrastructure works, Franken adds, "Decommissioning, heavy lifting structures are getting bigger and bigger."
The EVO-System combines high-pressure hydraulics with the high speed of today’s PLC-controlled systems. EVO-system may control 4, 8 or 12 points with one hydraulic power unit (HPU).
One standard PLC-controlled hydraulic power unit can be used for eight hydraulic movement functions with a 9in touch screen. The user can monitor movements and cylinder positions during the lifting procedure using a visual real-time presentation.
The EVO HPU is designed for single use with 4, 8 or 12 lifting points and can be extended into a network with up to four units. When operations require 2 or more HPUs, the networked system has to be controlled using a separate portable master control box.
It is a multi-functional system with 8 standard hydraulic movement modes to control most synchronous movement applications and capabilities: manual, pre-load, automatic, retract fast, depressurize, tilting, stage lifting (step- by-step) and centre of gravity.
PLC-controlled systems with warning and stop functions offer advantages over manual, multi-operator control approaches, the company says.
Programmable failsafe monitoring and safety alarms reduce the risk of structural damage by bending, twisting or tilting due to uneven weight distribution or load-shifts between lifting points. Partial automation of lifting processes also allows for increased productivity, as there is 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. The process does not have to be stopped after any incremental value, checked, manually re-measured and corrected.
Additional features of the system include network capability, enabling it to link up 4 hydraulic power units (HPU) to a separate master control box. It also has a wireless remote, a VFD motor, and a 3.0kW hydraulic power unit with 250ltr reservoir. Customers can use their existing standard Enerpac cylinders with the system.
As an option for more complex and demanding applications, the company offers the EVO-W Series (EVO-W System), containing additional control features for weighing systems with load cells.
