The challenge

In the biggest iron mine in Mexico, the unscheduled stoppage index for extraction front loaders increased greatly. In just 7 months the company lost 21 full hours of productivity due to equipment downtime.
The stoppages were caused by premature wear of joints and bushings in heavy-duty equipment. This caused the replacement of 7 bushings and 4 pins, generating costs of 30,000 USD in spare parts.
The maintenance team, in collaboration with a technical consultant form Interlub found the root of the problem: the lubricant in use wasn't able to endure the extreme loads that were required. And the presence of contaminants such and dust and mineral particles accelerated the wear.

The solution

Interlub's product development team designed Ultraplex 2 Moly Plus, a high-performance grease which contains solid lubricants and extreme pressure additives. This unique composition assures an optimal performance under extreme loads.

The results

The seven months after the team substituted the traditional grease with Ultraplex 2 Moly Plus was much more productive. The unscheduled stoppage index for front loaders and number of replaced spare parts fell to zero and the 21 full hours of productive time were recovered.
