QME 2014 Preview: Efficient hydraulics

An international market leader in high-pressure hydraulics, Enerpac, will display its latest workplace efficiency and safety technologies at this year's Queensland Mining Exhibition in Mackay from July 22-24. 

Enerpac – which operates in 22 countries with more than 1000 employees – will show advanced technologies ranging from its new XC cordless electric pumps and its latest non-impact professional bolting technologies, through to new generation Enerpac EVO synchronous lifting systems used to lift entire structures, plant or machinery weighing thousands of tons. 

Enerpac produces thousands of compact and powerful 700-bar (10,000 psi) high-pressure hydraulic products that are distributed worldwide, focusing on the design of products, from the smallest cylinder to complete computer-operated lifting and positioning systems, which increase productivity and make work safer and easier to perform. 

The Enerpac organisation has one of the world's most extensive ranges of high-pressure (700 bar) hydraulic technologies, with thousands of pumps, cylinders, fastening technologies, tools, systems and accessories.

XC Series cordless pumps offer the performance capabilities of an electric or pneumatic powered pump with the convenient portability of a hand pump. 

They satisfy the need for a long-lasting pump that can be used in remote and hard-to-access areas, being constructed of lightweight materials and equipped with a powerful, one-half horsepower motor and feature 28-volt, Lithium-Ion battery technology. 

New all-steel slimline WCR-4000 Series torque wrenches to be shown at QME offer more power, durability, accessibility and safety than any comparable tools of their size. 

The WCR 4000 spanner design has been optimized to provide the lowest radial and spanner thickness possible yet still deliver the rated torque required to provide bolting professionals with one of the most versatile and high performing tools available for limited access applications.

The drive unit for new WCR4000 range is compatible with widely used Enerpac standard W series hexagonal cassettes. 

The WCR4000 range joins Enerpac's wide range of non-impact professional bolting and joint technologies, above, including the W low profile hexagonal wrenches, S square drive wrenches, Z series torque wrench pumps and complementary technology such as the new ATM series flange alignment tools that rectify twists and rotational flange misalignment quickly and safely. The WCR 4000's slim spanner design resolves bolt-to-pipe restrictions and reduces bolt height restrictions, provides functionality on nearly any API flange.

Specialist staff will be on hand at QME to discuss the synchronous technologies employed in recent major Australasian projects, including use of new generation EVO PLC-controlled Synchronous Lifting systems used to manoeuvre a 3600-ton tunnel boring machine and Strand Lift systems used to lift a series of grinding mills in Western Australia weighing from 800-1500 tons. 

The mammoth tunnel boring machine, named Alice, is the largest tunnel boring machine ever deployed in the Southern Hemisphere has been safely and precisely sent into action using advanced Enerpac synchronous hydraulic technology to tilt, push and, when required, turn the machine. Enerpac EVO Synchronous Lifting System prepares to launch Alice, left, a smaller four-point EVO system, centre, and strand lifting ball mills, EVO is a new generation Enerpac synchronous lifting system that replaces manual control of hydraulic heavy lifting with PLC control of multiple cylinder lifts 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. 

The new 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.

Enerpac delivered two stage lifting sets both consisting of 4 BLS506 cylinders operated by a ZE split flow pump, which Mammoet used to install 98 conveyor sections as part of Rio Tinto's Western Turner Syncline Project, at their open pit mine 20km north-west of Tom Price. 

The stage lift sets were used to lower conveyors as part of the installation process. 

They were expected to lower one conveyor a day, but with the Enerpac pump system, Mammoet were able to lower four per day, increasing their efficiency fourfold, despite the rugged conditions of the site.
