South Australian steel profile cutting company, Ferrocut, has boosted effi ciency and enhanced its operators’ safety by installing over head cranes in its new factory and warehouse complex.

The cranes have been installed in the Techport Australia industry hub near Adelaide; Techport is the base for ASC, Australia’s largest defence shipbuilding organisation, which is delivering the Royal Australian Navy’s next generation $8 billion Hobart- class Air Warfare Destroyers.

The industry hub includes a 35-hectare supplier precinct for sub-contractors to establish operations and develop strong and efficient supply chains.

Heavy load

Ferrocut is supplying cut steel plate from its new facility to a range of industry customers, including engineering, infrastructure and mining groups as well as processing ship plate for the ASC. The company’s six new CXT cranes are being used to lift and transport steel plates and cut steel parts.

Some of the cranes have anti-sway controls that are installed on only about half a dozen over head cranes in Australia. Two of the cranes at fitted with Trunninger plate magnets, facilitating easy lifting and moving of large loads. Ferrocut equipment manager, Emile Ellens, is pleased with the results.

“It’s the first time we’ve used Konecranes overhead cranes. We chose them after speaking to other users, and because of the Konecranes reputation, and because their quality was bet ter,” he said.

“They’ve been very good. Their operation is nice and smooth, both longitudinally down the warehouse and also in the bogey movements across the warehouse.”

According to Ellens, Ferrocut is enjoying a few new, handy features offered by the cranes.

“The dual hoists on the pro duction cranes allow us to lift the steel plates from two points instead of one, which prevents the plates from rotating. We’re able to keep them all lined up the same way in the warehouse, resulting in safer and more efficient handling,” Ellens said.

“The anti-sway feature, which we hadn’t experienced before, works very well. It prevents the load from swaying during travel, which is a big safety issue. Anti- sway takes some of the pressure off the crane operators, who don’t have to be so experienced.

“Two of the cranes have electro-magnets fitted, which make the cranes more efficient and increase our productivity, because chains are not needed to lift the plates. The structure of the actual beams of the cranes is quite impressive. They are of very good quality and appear to be very strongly engineered.”

Safety and reliability

The world’s largest producer of overhead cranes and lifting equipment, Konecranes has reportedly built its most advanced safety, ergonomic and reliability technologies into its CXT series of industrial cranes and wire rope hoists. CXT cranes with individual hoist capacities up to 80 tonness are designed to be industry bench marks of safety and ergonomics, with easy and effective load han dling and optimum dimensions for maximising the hook travel.

Konecranes industrial cranes and hoists are used by many industries including automotive production, energy and resources, general manufacturing, metal and mineral processing, primary product and paper processing and ports and infra structure projects globally.

“Konecranes has over the years established a track record that includes a number of industry-firsts. The newest innovations are found in our groundbreaking CXT crane design, a type which is now in increasingly wide spread use throughout Australasia,” says Konecranes Australia national sales and marketing manager, Warren Ashton.

“Not only is the CXT hoist a forerunner in technological terms, the design innovation has reduced the number of maintenance and wear items on the hoist, thus reducing the cost of ownership for the end-user. Though we recommend Konecranes as the service provider of choice, any service agent with basic crane knowl edge and experience can effec tively maintain a CXT hoist through its lifetime.”

CXT cranes are said to have excellent hook approaches at both ends of the crane and the headroom requirement is mini mal. The cranes are designed to eliminate unused or under-utilised square meters because the crane can operate closer to the walls and lift the load higher.

Inverter controls are designed to deliver smooth starts, acceler ation and deceleration, which minimises load swing and enables fast and accurate load positioning. Konecranes Dynafamily inverter controls and pole changing controls are stan dard options for crane and trol ley travelling on CXT cranes.

CXT features also include high performance hoisting motors with 60 per cent ED rating, which combine extra power with superior cooling characteristics. The hoisting motors also have the power and flexibility for tem porary peak usage situations.

The units also offer inverter control as standard in crane and trolley travels, for easy and effective load control. Smooth starts and stops are said to reduce wear and mechanical stress on structures and minimise the load sway. Improved productivity is also achieved because moving and positioning the load is faster, easier and safer, according to the company.

To meet specific load handling capacity and factory size require ments, CXT cranes are available in single and double girder construction with profile or box girder design. Top connections and underhung main girder connections are available for different building heights and constructions.
