RUD-Erlau Delivers World’s Largest OTR Tyre Chains

Following the recent completion of a three year expanion and modernization programme of its Aalen, Germany, tyre protection chain (TPC) production facility; RUD-Erlau delivered and installed two full sets of the world’s largest TPCs last month. Called the R 75S Plus the TPCs have gone into service in both Europe and North America.

In Europe the R 75S Plus are protecting all four 52/80–57 tyres on a CAT 994 loading limestone. The other machine to be shod with R 75S Plus is a giant LeTourneau 1850 working iron ore in North America.

As a result of the deal RUD-Erlau retains the ‘world’s largest’ title it last claimed in 2004 when, in Japan, the front wheels of a Komatsu WA 1200 were fitted with a pair of TPCs providing full tread and side-wall protection against jagged rocks.

Weighing 4800kg each, the R 75S Plus has the same close-meshed structure as the recently introduced Fels X-19 TPC which, with it’s 19mm links, claims 30 per cent more service life in highly abrasive underground applications.

As with all RUD-Erlau TPCs, on-site support for the R 75S Plus will be available 24/7 from time-served RUD-Erlau-trained engineers.
