NOTE
The advantage of this equipmen
tversionis
that full advantage is taken of
the special free
lift height even in very low roo
ms (cellars, wag-
ons, ships).
FUNCTION: The fork carriage is lifted to the
special free lift height via the chain deflection
pulley of the centre cylinder. Here it moves
twice as fast as the centre cylinder. The inner
mast is then lifted via the two outer cylinders,
taking the fork carriage with it. The centre
cylinder is positioned on the extendable inner
mast.
Secure lifted duplex lift mast
DANGER
Check chain load!
Select safety chain with sufficient load bearing ca-
pacity for the lift mast. Take maximum lift height
into account.
