So - among other developments - built for years tracked vehicles for semi-caterpillar Diamond T, and disabled the service today in the Argentine Army. Caterpillars far exceeded expectations and who underwent exceptional efforts to be used in mountainous areas with floor slabs detached from the mountain that tested high tear strength required. Currently made to order to supply current owners and collectors of these historic vehicles.

The most important steel manufacture argentine company has employed the RONCAGLIA® SLEEVE for steel sheets coils winder and de-winder mandrels, since more than 30 years in his five plants.
The use of this rubber sleeve, allows:
1-to protect the steel sheet, the defects caused by the metallic mandrel, on the first loops. When a metallic mandrel is opened against the thin metallic sheets, usually a typical mark has been place, on the first loops, these loops have been rejected.
2-to replace metallic supplements for different I.D. coils. When it is necessary to produce coils with different internal diameters, the use of Roncaglia® rubber sleeve, instead of such heavy’s metallic supplements, assures faster and safer installation.
3-to protect mechanical mandrel systems. When you use Roncaglia® rubber sleeve, you have an additional advantage; you are protecting the mandrel mechanisms from dust, which can affect the normal operation.
