Abstract

Un carrello elevatore (10) ha un motore elettrico (16) di trazione, un motore elettrico che aziona una pompa per i circuiti idraulici, e batterie di accumulatori (19) che alimentano i motori elettrici. Al fine di ottenere lunga durata nonché affidabilità e prestazioni elevate, il motore di trazione (16) od entrambi i motori sono asincroni, ed inoltre sono previsti dispositivi (30) di rilevazione della posizione angolare e della velocità angolare dei motori ed un'unità elettronica (52) di pilotaggio e di controllo collegata ai dispositivi di rilevazione (30), che comanda l'alimentazione dei motori in funzione della velocità dei motori richiesta e sulla base dei dati forniti dai dispositivi di rilevazione.
