Hitachi EX850 Excavator Cylinder failures contained by Mag-Shield®
The Solution
Surrounding the existing reservoir suction screen with Bay6 Solutions’ Mag-Shield® filters captured and held contamination, preventing it from reaching the pump suction inlets. This also prevented contamination from collecting on the reservoir screen thus reducing the damaging consequences of cavitation.
Attached, is a photo of one of the Mag-Shield® after a cylinder failure on an EX850 excavator. Mag-Shield® captured material that would have spread throughout the machine. NACG saved a lot of money as we did not have to disassemble the hydraulic system for major cleaning. The actual savings estimate is greater than $70,000 and could be over $100,000. These estimates are compared to previous cylinder failures we have experienced with EX850s that did not have Mag-Shield®, which resulted in contaminated hydraulic systems.
