Use Of The Capacity Charts - Skyjack SJ643 TH Operating Manual

Section 5 – Operation

5.12 Use of the Capacity Charts

The capacity charts are located in the operator's cab.
They are used to determine maximum load capacity
for telehandler equipped with different attachment
combinations.
To properly use a particular capacity chart, the
operator must first determine the following:
1. Ensure the capacity chart is for the specific
telehandler model and the attachment.
2. Determine the weight of the load to be lifted.
3. Ensure that the load center for the load is
at or within the load center specified for the
attachment.
4. Determine the height where the load is to be
picked or placed.

5. Determine the reach where the load is to be
picked or placed
6. The maximum capacity is determined by the
intersection lines between height and reach on
the capacity chart. If the intersection of the lines
occurs at a division between capacity zones, the
smaller of the two capacity values must be used.
NOTE
The weight of the load must be equal to or less
than the number in the capacity zone.
WARNING
When handling loads, ensure that boom extension
indicator and boom angle indicator remain within
previously determined/calculated capacity zone.
