Get the Bradken advantage
- With over 100 years of experience in foundry operations, we offer high-quality, reliable products that have been designed with a holistic understanding of the casting process.
- Bradken's wholly owned, state-of-the-art foundry in Xuzhou, China was purpose-built in 2011 to produce crawler shoes. It can produce fully machined and assembled products covering a range of undercarriage parts for the 250T hydraulic excavators up to the 1400T electric rope shovels.
- We offer effective, site-specific solutions by employing superior components that minimise the effects of extreme environmental conditions.
- Bradken’s undercarriage components are designed to withstand the extreme mining conditions of the Arctic regions (Russia, Canada, Mongolia and Kazakhstan).
- Bradken’s proprietary alloys and processes maximise impact strength and toughness over a wide range of operating temperatures.
- While our alloys ensure reliable performance in extreme temperatures, we also carefully select our lubricants for our range of rollers and idlers.
- Bradken uses only the highest quality alloys to ensure component durability in corrosive environments.
- Bradken’s 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.
- All Bradken undercarriage for excavators designs are optimised to maximise wear face contact areas, minimising contact pressure and reducing the detrimental effect of abrasive wear.
- Bradken has experience in undercarriage solutions for high traction and high flotation applications.
- The technical experts from Bradken can tailor the designs to suit site-specific needs.
For your information: Bradken undercarriage components
Bradken offers an extensive range of undercarriage components, including return/load rollers, front idlers, and drive tumblers. These components are designed, engineered and manufactured to reliably perform in any mining condition, irrespective of the terrain.
Return or load rollers
Bradken rollers feature a one-piece forged shell, which eliminates unscheduled downtime caused by the roller falling due to the shell splitting into half. The rollers are supplied as a sealed, ready-to-install unit (including mounting hardware) with the option of oil or a grease-filled lubricant. This means the rollers do not have to be fitted to the auto lube system (if it exists). High-quality seals, bushes, axles, and axle retention systems offer dependable service life.
Front Idlers
Bradken front idler assembly designs are optimised to handle high impact loads and feature improvements to the thrust and bearing surface.
Drive Tumblers
Depending on the platform, Bradken drive tumblers are supplied in either high-grade, high-quality, induction hardened material or quench and tempered high-grade alloy, providing increased impact and wear characteristics. CNC-machined surfaces and the use of superior quality components ensure that the replacement parts are a consistent fit and are of optimum quality.
