STRUCTURE AND STABILITY OF THE LIFT TRUCK
1-28
The allowable load is stamped on the nameplate to show the
relationship regarding the position of the load center, the
height of the fork and the maximum load. Before loading the
forks, check that the load and load center are within the
permitted range on the stamped allowable load.
If the shape of the load is complex, set it so that the heaviest
part of the load is at the center of the forks and set the load
close to the load backrest.
If the forks are loaded more than the allowable value, the
drive wheels will float during travel and the steering system
will not work. This is very dangerous. Furthermore, the lift
truck will tip over easily under this condition. Therefore, be
sure to keep the load below the allowable value and properly
balanced.
ALLOWABLE LOAD
This shows the relationship between the position of the load center and
the maximum load. Before loading the forks, check that the load and
load center are within the permitted range on the load capacity chart. If
the shape of the load is complex, set so that the heaviest part of the load
is at the center of the forks and set the load close to the load backrest.
LOAD CAPACITY CHART
The load chart given here is an example. Always follow the load
chart stuck to the truck when carrying out operation.
1.
Permissible load
2.
Distance from perpendicular front face of forks to center of
load
3.
Permissible load curve when a mast with a maxi-mum lift-
ing height of 5 m or less is installed
4.
Permissible load curve when a mast with a maxi-mum lift-
ing height of more than 5.5 m up to 6 m is installed
5.
Example: When the load center is 60 cm with a 6 m maxi-
mum lifting height mast installed, the permissible load is 4.4
tons.
6.
Even if the load center is less than 60 cm, the permissible
load (4.4 tons) does not change.
7.
If forks are installed and the load center is 100 cm, the per-
missible load becomes approximately 3.2 ton.
