Abstract

"GUINDASTE HIDRáULICO TELESCóPICO DE MúLTIPLOS ESTáGIOS" O objetivo principal da presente invenção é o fornecimento de um guindaste hidráulico telscópico (10) que é significativamente mais leve do que os guindastes de tipos semelhantes. O guindaste hidráulico telescópico (10) é feito de tubulação de alumínio trefilado sobre manual (DOM) que consiste em uma liga especialmente formulada. O guindaste é de ação rápida, tem uma vida rolamento mais longa, e respiradores (94, 96, 98, 100, 102) para os espaços entre os estágios hidráulicos, para impedir que a sujeira seja sugada para o mecanismo hidráulico.
