Minetek a \u00e9t\u00e9 charg\u00e9 de concevoir et de fabriquer le premier ensemble d'att\u00e9nuation sonore au monde pour l'excavatrice mini\u00e8re Liebherr R9800. L'objectif du projet \u00e9tait de r\u00e9duire le bruit de fonctionnement de la machine jusqu'au niveau de bruit du site sans compromettre la capacit\u00e9 de fonctionnement de la machine, ajouter un poids excessif \u00e0 la machine ou restreindre l'acc\u00e8s pour la maintenance et l'entretien de routine.<\/p>\n

Avec l'installation de l'ensemble d'att\u00e9nuation sonore, le Liebherr R9800 fonctionne \u00e0 un niveau de bruit incroyablement bas de 114 dBA - une r\u00e9duction sonore de 12 dBA qui a permis \u00e0 notre client de l'industrie mini\u00e8re de la Hunter Valley d'utiliser la machine \u00e0 1 000 m plus pr\u00e8s de la limite\/du r\u00e9cepteur sonore.<\/p>\n<\/div>","protected":false},"featured_media":3718,"template":"","categories":[7],"tags":[18,103],"class_list":["post-1969","ra-download","type-ra-download","status-publish","has-post-thumbnail","hentry","category-sound","tag-case-study","tag-liebherr"],"acf":[],"yoast_head":"\nSound | Liebherr R9800 Excavator case study -
