How does the effective weight of a slowed extension relate to the actual weight of the extension?
Higher than the actual weight.
When load radius is between radii values, the operator must use the:
longer radius
Why should only approved attachments or extra counterweights provided by the manufacturer be placed on the rear
of the crane?
They could cause a backward stability problem.
A mobile crane's jib is offset 15º versus its original 0º offset, but the boom angle remains unchanged. In this situation,
the load radius:
increases
Abruptly stopping a rapid swing on a long-boom mobile crane will produce what major effect?
Collapsing the boom.
