Product
Bradken OC7495S79-3A Induction
Hardened Crawler Shoes
Situation
Our customer operates multiple 7495 electric rope shovels in a major Colombian coal mine. The mine plan requires higher than standard tramming of the shovels, resulting in elevated wear of the tracks and therefore reducing service life.
The OEM supplied shoes only achieve approximately 15k hours in these conditions with intermittent failures occurring during service without warning. In addition to this, the shoes can lose their pin eye bushes, causing pins to break and the track to separate.
Low wear life and intermittent shoe failures cost the customer in unplanned downtime, increased maintenance, and extra spend on product replacement.
Solution
Since 2015, Bradken has supplied over 380 shoes to this mine site to support their 7495 shovels and, during this time there have been nil failures of Bradken shoes. However, during the same time, the site has experienced multiple events where the OEM supplied shoes have failed in-service without warning, causing unplanned downtime on the machines.
With the installation of
Bradken shoes on the sites shovels the site has improved production rates, efficiency and safety by eliminating unplanned downtime due to shoe failure and maintenance. They can now typically achieve 25k hours at this site, where the OEM tracks rarely achieve more than 15k hours.
