A multinational producer of steel, producing some 70 million tons of steel per year operates 37 steel plants in 16 countries and 12 mining operations in nine countries. At one of their sites they use a large bucket excavator to move raw materials in their Reception and Storage devision.
Lubricating a mechanical bucket excavator cylinder.
Usually the mechanical screw-nut cylinder is not lubricated, but given the age of the excavator, the customer decided to lubricate the screw-nut system with Castrol's Optigear BM 460. Although the oil gives full satisfaction, it must be applied at least once a week, witch is a costly and time-consuming operation.
A MEMOLUB® HPS lubrication system, with the MEMOLUB® OIL R-500 refillable and reusable oil reservoir was installed.
- A 75% more efficient operation as maintenance crews only need to visit the site once a month to top up the oil reservoir.
- Regular and effective application of Optigear BM 460 to the screw-nut assembly.
