Abstract

La presente invenzione propone una soluzione al problema del disallineamento orizzontale delle pedane (1, 2) di un sollevatore elettroidraulico a doppia pedana durante le fasi di sollevamento e di abbassamento, così da consentire in ogni istante il controllo della quota di dette pedane (1, 2), e di effettuare in tempo reale le eventuali correzioni necessarie all'immediato riallineamento relativo delle pedane (1, 2) stesse.
