Jungheinrich DFG 425 Operating Instructions Manual page 68

Stack cylindrical loads close to each other and evenly. Place each row on boards and
secure each end with wedges.
Cylindrical objects can also be stacked in pyramids. Place wedges on the lowest row
of each roller.
Stack boxed pallets level and at right angles to each other. Stack the top row in the
opposite direction for extra safety.
Handling individual swaying loads
With forklift trucks which have a hook auxiliary attached to the fork arm (or some other
equipment that allows loads to be suspended by a hook), there is a tendency that
these destabilizing forces will impact on the truck. With forklift trucks that have been
modified for this purpose, the following guidelines must be maintained to improve
truck stability.
Z
A truck that has been modified to transport loads by a hook is by definition a crane
and hence the corresponding crane regulations apply.
When handling suspended loads, the max. speed (laden) on a level surface must be
restricted to 17 km/h.
The forklift truck's capacity is reduced if it has been modified to transport loads from
a hook. The following details can be found on the data plate on the auxiliary vehicle
or driver's cab.
– Weight of auxiliary vehicle;
– Centre of gravity:
– Rated capacity.
F
The rated capacity of the truck and the auxiliary vehicle must not be exceeded.
– The hook must not be raised more than 4.5 m above ground height.
– When travelling, the lower section of the load must not be raised more than 300 mm
from ground level or the forklift truck (whichever is the lower). The mast must be
tilted either almost vertically or backward.
– The forklift truck must only be operated on stable, constant, even and prepared
surfaces.
– Only ever transport a single load at a time.
F
If the forklift truck is not properly operated, it may tip over and result in injury to
personnel. If the forklift truck is about to tip over:
– Remain within the truck (do not jump out);
– Hold onto the steering wheel;
– Brace your feet;
– Lean away from the point of contact.
