ESCO Corporation, the leading global provider of wear parts and attachments for the mining and infrastructure industries, debuted its new Nemisys lip system at MINExpo 2012 recently. The new system, which features a cast or plate lip with shrouds and a three-piece tooth system, is used on large mining buckets. The Nemisys system is now available for hydraulic mining excavators in the 300 to 800 t classes. The system will also be made available for cable shovels and draglines.

ESCO engineered the Nemisys system from the ground up. The lip, shrouds and teeth were developed simultaneously under a new engineering process designed to maximise a machine’s productivity. “The ESCO Nemisys system was designed to give customers a safer and highly productive solution to their mining needs,” said Jon Owens, ESCO’s Senior Vice President and President of the Engineered Products Group. “ESCO is known as a leader in quality and innovation, and with the Nemisys system we continue to raise the bar in our industry.” Testing of the new system indicates that compared to legacy systems, the lip design and ground engaging teeth require on average 10% less force to penetrate; teeth have up to 19% more usable wear metal; and the system on average weighs 7% less.

These improvements provide customers with increased productivity and reliability while reducing maintenance costs. Integral hammerless       locking devices on points, adapters and shrouds and improved ergonomics also make the system safer for customers. The Nemisys system for hydraulic mining excavators is available now. Larger system sizes will roll out to the market between now and October 2013.
