SIDE-STOW JIB
Jibs are rated by boom angle only and not by radius. This means that as long as
the boom is at 61° boom angle and the jib at 30° offset, before loading, no matter
if the boom is fully extended or retracted, it can only lift a maximum of 3,300 lbs.
on a 33 foot side-stow jib. The radius shown in the jib chart is the expected
radius with a fully extended boom and jib after loading and deflection.
Never use a jib for clamshell or magnet operation. The heavy side load due to
swinging and bouncing that can occur could damage jib or boom point. This is
also true of pick and carry operations.
Example
Hook & Ball 239 lbs.
Slings 300 lbs.
Object Lifted 2500 lbs.
Total Load Lifted 3039 lbs.
In this example the total load lifted is 3039 lbs. The boom angle is 61º, the jib is at the 30º
offset and the machine is in outriggers. In this case the load can be safely lifted.
