Contamination Control Filtration Skid for Caterpillar

Contamination Control Filtration for Cat Hydraulic Mining Shovel


The problem

The condition of the operating fluid plays a key role on the lifetime of a hydraulic system; approximately 70% of all breakdowns can be attributed to the condition of the oil, with proven detrimental effects on the efficiency and profitability of systems and equipment.

The solution

In order to address this issue, Caterpillar has partnered with HYDAC Australia to supply its Contamination Control Filtration Cart for the Hydraulic Mining Shovels HMS 6015-6090. This product allows machine owners to achieve lowest owning and operating cost on their Cat products.

Field Test on 6060 shovels at Rolleston mine, QLD

The test was done to identify the cleaning and filtering capabilities of the filtration skid, ISO reading codes, hose lengths, connections, transporting, etc…

The first test on 10 of October 2017 was done in just 40 minutes runtime, and the filtration procedure cleaned the oil in the hydraulic tank by 3-4 ISO codes; the first reading on the onboard HYDAC Contamination Sensor was 19/18/16 and the last one was 16/15/12.

The filtration of the oil in the hydraulic tank was successful, even though the procedure was done in just a fraction of the recommended time (1 hour).
