Challenge A fleet of Hitachi EX5600 excavators operated at a Queensland coal mine were suffering lost time due to high rates of Contamination Sensor Alarms.  These alarms necessitated stopping the machine while maintenance checked and cleaned the sensors before the machine could start again. 
Further, the elevated levels of iron in the machine's hydraulic system were causing reduced component life.  Solution After hearing of success with similar Hitachi machines...

    Here are some examples of hydraulic failure clean-up in mining trucks, excavators, dozers, loaders. 
Mag-Shield removes iron from contaminated systems, allows fast repairs with no follow-on failures.   1. Mag Shield in CAT 793D after normal operation                               2. CAT 777F after component failure   Find out more about Mag-Shield here or contact s...

 

 

A - Rare earth magnetic filtration systems remove most, but not all iron contamination from hydraulic systems; typically 60-70%.  The effect on oil analysis is that any trends in iron remain intact, just at a lower base-line.

Combat iron contamination and minimise hydraulic failure Our mission at ZEMEK Engineering is to improve the lifecycle performance of mining equipment. We're always on the lookout for new products that increase reliability and protect against failure. Mag-Shield filters meet those needs and deliver a multitude of benefits. Manufactured by BAY6 Solutions, Mag-Shield filters use rare and advanced earth temperature resistant magnetic technology to direct the oil flow in your mining equi...
