Michelin North America has introduced a new size of MICHELIN® XDR® 3 haul tyres as it looks to, it says, address the productivity and endurance issues found in today’s surface mines.
The XDR3, Michelin’s most popular surface mine tyre, the company says, was developed for a range of rigid dump trucks with payload capacities up to 400 tons (363 t). The new 37.00R57 size not only expands the MICHELIN XDR3 portfolio to seven sizes, but also replaces the MICHELIN XDR2 line, it said.
Jake Thompson, Michelin North America’s B2B Mining Marketing Manager, said: “Michelin provides solutions that support safety improvements, operational cost reductions and innovation at mines worldwide. This new tyre combines the latest technologies from the 200 professionals working at our R&D centre.”
The latest release comes less than four months after Michelin North America released the 27.00R49 size XDR3.
Tested under extreme conditions before its launch, the MICHELIN XDR3 is designed for operator safety, Michelin says, with its tread pattern providing excellent load distribution across the contact patch. This also lowers contact pressure, improves wear and increases tyre life by a minimum of 8%, according to the company.
In addition, interlocking blocks of rubber on the shoulder help reduce wear. As previously stated, the XDR3 is MEMS-ready to capture and transmit temperature and pressure information in real time. The MEMS patch is also compatible with tyre additives and is RFID equipped.
With 10% stronger corrosion-proof cables incorporated into the tyre architecture, the tyre provides a significant upgrade in situations where this equipment is operated for up to 23 h/d in extreme terrain, the company said.
