Xtreme XRM1145 - Using Load Capacity Charts; Reading Load Capacity Charts

Using Load Capacity Charts
The reach forklift includes two (2) indicators to assist
the operator for accurately using the load capacity
charts. These indicators are the Boom Extend
Letters and the Boom Angle Indicator.
Boom extend letters are located
on the left side of
the boom and visible to the operator
as the boom is
extended. These letters indicate boom extension
as
it corresponds to the load capacity charts.
NOTE: For example, when letter
"A" first appears,
the boom extension corresponds
to the arc of line "A"
throughout all the load capacity charts.
Figure 7-44. Boom Extend Letters.
The boom angle indicator is located on the left side
of the boom
and is visible from the operator's seat.
Use the boom angle indicator
to determine the boom
angle when referring
to load capacity charts.
NOTE: The boom angle indicator
is a plumb arrow
with angular graduations from -5
to +70

Reading Load Capacity Charts
To accurately read the load capacity charts, you
must determine three
(3) things:
o Weight of load being lifted.
o Height of structure where load is to be placed.
o Distance from front tires where load will be
placed.
For example:
1. The operator determines load weight and makes
sure load does not exceed fork, attachment, or
boom capacity.
The load
is 4000 pounds (1814 kg).
2. The operator safely moves the load to a loading
position:
• places forks under load
o tilts and raises load safely
o fully retracts boom
• drives vehicle to position perpendicular to
structure
• levels the vehicle.
3. The operator determines height of structure
where load is to
be placed.
The structure height is 20 feet
(6.1 meters) from
ground level.
4. The operator determines distance from front tires
where load will
be placed.
The distance
in front of vehicle where load will be
placed is 17 feet (5.2 meters).
5. Operator reads load capacity chart for type of
tires and attachment carriage
to learn it will be
safe to place the load if the boom extend letter
"D" has appeared and boom angle indicator read-
ing does not go below approximately 40 degrees.
This condition, however,
is the maximum limit for
this specific load weight, structure height,
and
placing distance.
