It allowed the shopping centre to continue operating beneath, and we didn’t have to set up expensive scaffolding or work solely at night just to build them in their final location. Pulling them across with Enerpac’s EVO system saved significant downtime in that regard,” he says. Enerpac EVO system control of multiple cylinder lifts, shifts and positioning offers accuracy, safety and productivity benefits for precision lifting of heavy resources industry machinery. The EVO system is the evolutionary result of Enerpac’ s 25 years of experience in specialised hydraulic engineering and lifting technology using digitally controlled hydraulics to accurately and safely lift some of the largest and most challenging structures on earth, including mineral and oil and gas processing equipment. Recent examples range from 1500 ton grinding mills in Western Australia to the super lifting and launch of a 43,000 ton floating oil production system in Malaysia for the Gumusut-Kakap offshore field. The latest EVO synchronous system offers eight standard hydraulic control modes and can control 4, 8 or 12 points with one hydraulic power unit (HPU). A master control unit is also available that offers daisy chain control of up to 16 EVO systems, giving a maximum of 192 lifting points. Instead of whole teams of lifting personnel trying to manually co-ordinate with each other lifts by hydraulic cylinders dispersed around a job, the EVO Series synchronous lifting system integrates the high-pressure hydraulic cylinders involved with a PLC system to monitor and control precise movement and positioning of heavy loads. Through an integrated HMI (Human Machine Interface), all movements are managed from a central control position that displays live operation with real-time status updates for each lifting position. The multifunctional EVO-Series can be used with multiple standard 700 bar (10,000 psi) single- or double acting cylinders and is offered with a 5 HP or 10 HP hydraulic power unit with 250 litre (66 gallon) reservoir. The EVO-W system comes with built-in calibrated sensors so that it can also perform weighing and centre of gravity determination, vital for precision lifting, shifting and movement tasks.
