Duplex lift mast
NOTE
The benefit of this design is that full advantage
is taken of the special free lift height even in
very low rooms (cellars, wagons, ships).
FUNCTION: The fork carriage is raised to the
special free lift height by the chain guide pulley
of the centre cylinder. Here, it moves twice as
fast as the centre cylinder. The inner mast is
then lifted by the two outer cylinders, taking
the fork carriage with it. The centre cylinder is
positioned on the extendable inner mast.
