XRM 9 45 Operation
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:
• Weight of load being lifted.
• Height of structure where load is to be placed.
• 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
• tilts and raises load safely
• fully retracts boom
• drives forklift to position perpendicular to structure
• levels the forklift.
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 forklift 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 reading does not
go below approximately 40 degrees. This condition,
however, is the maximum limit for this specific load
weight, structure height, and placing distance.
