shall be considered as part of the load. The weights for
these items is stated on the capacity chart.
4.
Rating on outriggers are for either outriggers fully
extended.
5.
Ratings on rubber depend on tire capacity, condition of
the tires and proper inflation pressure of 120 psi (827
kPa). Loads on rubber may be transported at a
maximum speed of 2.5 mph (4 km/h) on a smooth level
surface with the boom retracted to the shortest length
possible and centered over the front. Do not use the
boom extension with the crane on rubber.
6.
For operating radius not shown on the Load Rating and
Range Diagram Chart, use load rating of the next larger
radius.
7.
With a load both on the boom (pick and carry) and on the
cranes’s deck the maximum combined load is 16,000 lb.
(7258 kg). The maximum load that can be placed only
on the deck with nothing attached to the boom is 20,000
lb. (9070 kg).
8.
Do not induce any external side loads to the boom or the
boom extension.
Determining Lift Capacity at the Boom
Extension
The boom extension increases the length of the boom
assembly by 15 feet (4.57 m).
The capacity of the boom extension is determined in two (2)
steps. First, as with the main boom, check the main capacity
chart after determining the operating radius. These
capacities are based on main boom strength and machine
stability. Second, check the boom extension (jib boom)
structural capacities after determining boom angle. These
limits are based on the boom extension structural strength.
Use the lesser of these two capacities such that neither is
exceeded.
NOTE:
Exceeding the Capacity is dangerous and voids the
crane’s warranty.
Pick and Carry Ranges
Figure 4-2 illustrates the range of operation for pick and
carry loads. Do not pick and carry outside of the specified
ranges. The crane could become unstable and tip over.
