72 Model 944E Origin 3/04
Operation
To accurately use the capacity chart, the operator must first determine three
important things:
1. Weight of the load being lifted.
2. Height of the structure where the load is to be placed.
3. Distance where the load will ultimately be placed in front of the front tires.
Reading Capacity Charts
Example: (1)
1. The operator has placed the load onto the forks, fully retracted the boom,
positioned the vehicle perpendicular to the structure and leveled the vehi-
cle.
2. The operator determines that:
ï The weight of the load is 7,000 pounds (3.175 kg).
ï The height of the structure the load is to be placed upon is 28 feet
(8,5 meters) from ground level.
ï The distance where the load will ultimately be placed in front of the
vehicle is 13 feet (4 meters) from the front of the tires.
ï The transfer carriage will remain fully retracted (0").
3. After applying the height of the structure and the distance of load place-
ment away from the vehicle to the sample capacity chart, the operator
knows that it will be safe to place the load if the boom extend letter for zone
ìEî has not started to show and the boom angle indicator reading does not
go below approximately 48 and the transfer carriage will remain fully
retracted.
This condition is, however, a maximum limit for this weight, height and distance away
from the vehicle. The operator should move the vehicle closer to the structure to
assure that the vehicle will not exceed the maximum limits for placing the load.
IMPORTANT! When using the PlaceAceô transfer carriage to place a load, be sure
to refer to the appropriate load chart that depicts the operation (movement) of the
transfer carriage (1" to 80"). This chart applies to any movement of the transfer
carriage. The load charts are reproduced at the end of this manual in the ìLoad
Chartî section.
To accurately identify the load charts that apply, refer to the
following icons which are also located in the upper right
hand corner of each load chart.
ï Use for any forward movement (1" to 80") of the
transfer carriage.
ï Use for 0" of transfer carriage movement. Fully
retracted position only.
WARNING:
DO NOT exceed rated capacities! Any attempt to lift
or carry loads in excess of those shown on the capacity chart may cause
vehicle tipover, loss of load or structural damage which could result in
death or serious personal injury.
