LOAD RATING CHART INTERPRETATION
In the following pages are examples of a load chart, these example charts may differ from
the chart supplied with your crane. Always use the load rating chart supplied with the crane
to interpret the conditions and limitations that exist when making a lift with the crane. The
determining factors are lifted load, radius, boom angle, working position, hoist line reeving,
tire pressure, travel data, use of jib, and any other special conditions that exits, such as
wind velocity, soil conditions, etc.
a) LOAD RATING TABLE
How to look up rated lifting capacity:
Find out the suitable boom length according to the lifting height and working radius in
lifting height chart, and then find out the rated lifting capacity from the load rating chart
according to the boom length;
NOTE:
If lift a load with the jib assembled, find out the rated lifting capacity according
to the boom angle listed in the load rating chart.
For example:
If the outrigger beams are fully extended and the boom is over side or over rear,
determine the rated lifting capacity according to the following figure:
Fig. 07 - 6
Find out the corresponding rated lifting capacity according to actual working
conditions.
The rated lifting capacity:
If the boom length is L2
m, the rated lifting capacity is W
2
kg
.
If the boom length is L3
m, the rated lifting capacity is W
3
kg
.
