Abstract

Si descrive un dispositivo di sollevamento da utilizzare in particolare nei banchi di prova di aeromobili come elicotteri e piccoli velivoli, costituito da un complesso estendibile, azionato elettricamente, con dei manicotti coassiali scorrevoli per avvitamento uno sull'altro ed un'asta telescopica, solidale alla base del martinetto e posizionata al centro del complesso di manicotti, che vincola rotoidalmente, con l'ultimo dei suoi bracci estendibili, il manicotto più interno, nel quale può scorrere assialmente. Il manicotto più esterno riceve il moto da una boccola filettata che è messa in rotazione da un meccanismo vite senza fine - corona dentata e ruota in senso inverso svitandosi per reazione rispetto alla boccola filettata in quanto tutti i restanti manicotti, impegnati l'un l'altro, sono impediti a ruotare dall'asta telescopica. La stessa cosa si ripete in fasi successive per i restanti manicotti senza necessità di vincolare il martinetto.
