RATED LIFTING CAPACITIES.
There are two graphical presentations of the rated lifting capacities. One provides for lifting on outriggers over the side
while the other provides capacities for lifting on outriggers over the rear. The numbers on the vertical axis signify the radius
in feet. The horizontal axis shows the boom length in feet. The figure in each block represents the rated lifting capacity in
pounds at that particular radius and with that particular boom length. Each block also shows a figure in parentheses. This
figure represents the boom angle at that particular radius and boom length.
The following information comes from the load chart in regards to the rated lifting capacity charts.
1.
Capacities appearing above bold line are based on structural strength and tipping should not be relied upon as a
capacity limitation. Capacities do not exceed 85% of tipping loads as determined by test in accordance with SAE
J-765.
2.
Capacities for 33 ft. boom length shall be lifted with boom fully retracted, capacities shall not exceed those shown
for the 38 ft. boom length.
3.
For boom lengths less than 112 ft. with 32 ft. boom extension erected, the rated loads are determined by boom
angle only in the column headed by 112 ft. boom.
4
. For boom angle not shown, use rating of next lower boom angle.
5.
Boom angle is the included angle between horizontal and the axis of the boom base section after lifting rated load.
(See A6-829-002833 for boom angles).
