5.3.1 - FORKLIFT HANDLING METHOD

HAZARD!

It is forbidden to:
• Do not transit under suspended loads;
• Do not move the load over the personnel operating in the site/plant area.

WARNING!

The following is not allowed on forklifts:
• carrying passengers;
• lifting people.

NOTICE!

Packaging must always be handled in a vertical position

Proceed as shown in tab. 5.33:

Posizionare le forche del carrello elevatore sotto il piano del carico.

Assicurarsi che le forche fuoriescano dalla parte anteriore del carico (almeno 5 cm), per una lunghezza

sufficiente ad eliminare eventuali rischi di ribaltamento della parte trasportata.

Sollevare lentamente il carico di qualche decina di centimetri e verificarne la stabilità facendo attenzio-

ne che il baricentro del carico sia posizionato al centro delle forche di sollevamento.

Inclinare il montante all’indietro (verso il posto guida) per avvantaggiare il momento ribaltante e

garantire una maggiore stabilità del carico durante il trasporto.

Adeguare la velocità di trasporto in base alla pavimentazione ed al tipo di carico, evitando manovre

brusche.

7

Posizionare il carico nella zona prescelta.

Sollevare le forche fino al contatto col carico.

Nota: se necessario fissare il carico alle forche con morsetti o dispositivi similari.

2

Make sure that the forks protrude from the front of the load (by at
least 5 cm), far enough to eliminate any risk of the transported load
tipping.
