CAT 994H
A Mag-Shield® kit was fitted in the steering and brake tank to provide additional and complementary filtration.
Challenges
An Australian coal miner operating CAT 994H loaders was continually experiencing a high frequency of component failures due to heavily contaminated oil, resulting from contaminants not captured by standard media filters.
After experiencing first-hand the benefits of fitting Mag-Shield® products to their hydraulic tanks, they chose to fit Mag-Shield® to the steering & brake tank. Like the main hydraulic circuit, the goals were to keep the steering & brake fluid clean, reduce frequency of failure and extend component life.
Solution
A Mag-Shield® kit was fitted in the steering and brake tank to provide additional and complementary filtration. As contaminated fluid circulates and returns to tank, ferrous material is captured by the Mag-Shield® preventing contamination of the entire system. This becomes even more consequential post failure as Mag-Shield® stop very large amounts of generated debris circulating and damaging system components.
Results
The performance of the Mag-Shield® was monitored for a period of 5000 hrs. No failures were experienced during this time frame. Over the course of normal operation, 50 grams of ferrous material was collected by Mag-Shield®
Capturing the material produced during normal operation is key to improving oil cleanliness and component life which helps mitigate failures. This results in less disruption to mine site operations, improved availability and very significant savings.
