We are one of the largest manufacturers of crawler and undercarriage systems for mining machines over 200T. Over the past 25 years, we’ve manufactured and supplied more than 200,000 crawler shoes for mining customers worldwide.By focusing on our customers’ undercarriage requirements we are able to offer effective, site-specific solutions, that provide superior performance with minimal maintenance.
Our unique induction hardening processes achieve greater case depth than competitor products, resulting in greater wear life of these components. Our proprietary, through-hardened alloy, offers an alternative unique to Bradken undercarriage products, prolonging shoe life in systems that have sufficient space for interconnecting parts to wear. Finally, all Bradken undercarriage designs are optimised to maximise wear face contact areas, minimising contact pressure and reducing the detrimental effect of abrasive wear.
High toughness connecting pins are manufactured from induction hardened NiCrMo steel, resulting in reduced pin failures and unscheduled downtime thus increasing machine availability.Over the years, mine operations have experienced unscheduled downtime that is related to failure of connecting pins and hardware – even leading to crawler shoe failure. Bradken has applied the same design review principles to these aspects of our products ensuring there is no “Weakest Link”.
Bradken ERS crawler shoes feature either induction hardened alloy or austenitic manganese steel providing superior wear resistance and increased service life for any mining application. State of the art design, materials selection and manufacturing processes equate to dependable performance.
Even in the worn condition, our shoes are designed to incorporate superior factors of safety, so that overload failure is less likely. This gives users confidence to change parts on condition rather than hours alone.
