La Hitachi ha progettato un ascensore capace di salire 1'200 metri al minuto, altrimenti detto 95 piani in 43 secondi. Un primato che polverizza il precedente, detenuto da una cabina installata in un grattacielo di Taiwan, capace d'elevarsi di 1'010 metri in un minuto.
Gli ingegneri del gruppo nipponico hanno ottenuto la prestazione grazie alla messa a punto d'un potente motore e di cavi del 30% più leggeri di quelli tradizionali.
Il primo modello sarà installato su una torre di 111 piani, per 530 metri di altezza, in corso di costruzione a Guangzhou, in Cina.
