a stacker crane is a universal means
of transport that can be used in
warehousing and production. Unlike
a conventional forklift or side loader,
aisles are not required, as the stacker
crane works from above. the telescopic
mast is suspended from the single or
double-girder crane, allowing it to cover
the area. even passing over racks and
other obstacles can be done without
difficulty. a further advantage is the
small space requirement. even a forklift
requires an aisle that it is as wide as
the vehicle – but not our stacker crane.
since the fork tips can be rotated 90º,
only a minimal aisle is needed to allow
the lifting mast to pass through. the lifting
mast can be continuously rotated
through 360º. to load lorries standing
at an angle, for example, the forks can
be tilted from +7.5º to - 2.5º.
from euro pallets to
wooden beams
a further advantage is the adjustability of
the distance between forks. from 600
mm fork spacing for euro pallets up to
3,600 mm for wooden beams or sheet
steel. this allows the load to be moved
correctly and safely, in accordance with
the goods being transported. the stacker
crane can also be fitted with vacuum
or magnetic grippers as an option.
changeover systems for various lifting
means or add-on equipment are possible.
all the way up to a fully
automatic storage
and retrieval machine
the stacker crane can be operated with
floor or radio remote control, like normal
hall cranes. as an option, it can also be
used in fully automatic mode to service a
pallet rack for example. command input
can be done with touch screen panels.
Distance measuring systems allow the
controls to always know the position of
the crane. combinations are also possible.
the rear of the hall can thus be used
as an automatic sheet metal warehouse,
while the manually-controlled crane supports
production at the front of the hall.
simply a multi-talented crane.

ADVANTAGES OF THE STAckER cRANE
the stacker crane is often compared with the forklift. there are several factors
that speak in favour of the forklift. however, the stacker crane is superior
in several respects. thanks to the moveable forks, it can also be compared with
the side loader. We want to show you a few advantages of the stacker crane,
compared with the forklift and side loader.
aisles are not required
a stacker crane works from above.
this means that it is not dependent
upon a traversable aisle. crowded warehouse
floors are no obstacle for the stacker
crane.
blocked aisle – an obstacle for the forklift
blocked aisle – no problem for the stacker crane
Closer stacks – more
storage volume in
the same floor area
for example, a stack distance of only the
width of the telescopic mast is required
to access the stack in a roof frame
warehouse, thanks to the rotating fork
tips. the fork carrier moves between
the empty spaces, swivels the forks out
and lifts the top frame.
example: stacked wooden beams
thanks to the rotating forks, only narrow aisles
are required
moving around
on different levels
if a fabrication building includes different
levels, such as a loading ramp, this does
not present an obstacle for the stacker
crane. even storage racks that stand in
a depression are not a problem for our
multi-talented crane!
fork tilt
the fork tips can be tilted just as with a
forklift or side loader. for example, this
allows loading and unloading of lorries
standing at an angle.
Loading ramp – different levels
Lorries standing at an angle – the stacker crane
can tilt its forks
Different add-on equipment
forks are not always the fastest handling
equipment. Different add-on equipment
is available for such situations. from vacuum
equipment to client-specific grippers,
we have the solution for your material
handling problem! You need the
fork carrier to unload lorries, but prefer
to supply your machines using vacuum
equipment? We can equip the stacker
crane with a fast-change system and
you can use the stacker crane as a universal
machine in your production!
fast changeover system – example:
fork carrier / vacuum gripper
economic benefit
You will obtain considerable cost benefits
from the 30–40% increase in
warehouse capacity. numerous automation
options bring additional benefits.
We would be happy to show you how
your company can achieve an optimal
cost-benefit relationship.
