Catastrophic Damage

In recent years public forest owners in the canton of Argovia have carried out considerable structural changes. The positive consequences to the accounts arising from these changes can be confirmed and documented using a number of various measurements from the forest accounts. Until 1999 the results of structural changes compensated for the decrease in wood revenues, even managing in some cases to move from loss to profit. The falls in profit following the catastrophic damage caused by the hurricane Lothar in December 1999 also meant falling accounts. Even in internationally comparable enterprise structures, the survival of forest enterprises is not assured at these low levels. Against a background of, above all, falling subventions without corresponding compensation, further structural changes are unavoidable. Such changes, however, can only lead to success if value is added along the entire production chain and the branch of forest and wood management is able to compete internationally.

Proactive Maintenance

Abstract In the engineering practice, knowing the technical condition of industrial equipment under operating results shortening of repairs, repairs machinery to smart planning based on the time evolution of bearing wear, detect and correct errors on their installation or repair. This is one of the most important objectives of proactive maintenance; maintenance engineer must follow and monitor the wear of equipment with moving parts to prevent damage and removing them permanently from service, ensuring repair costs as low as possible. The aim of this paper is to present a particular case study on vibro- acoustic diagnosis of equipment and components subject to wear during operation to prevent catastrophic damage, as well as human and material losses.
