The rated total load chart provides the maximum loads that the crane is capable of hoisting objects in
parallel with the length of the boom. The loads are specified by working radius.
[1] BOOM LENGTH
The following figures illustrate the condition of the booms, “Boom (1)”, “Boom (1) + (2)”, “Boom (1) + (2) +
(3)”, “Boom (1) + (2) + (3) + (4)”, and “Boom (1) + (2) + (3) + (4) +(5)” in the preceding boxes in the rated
total load chart.
1. “Boom (1)”: All the booms are retracted.
2. “Boom (1) + (2)”: With booms (3), (4), and (5) retracted, boom (2) is fully extended.
“Boom (1) + (2)” is to apply to crane operation with boom (2) extended even if only slightly.
3. “Boom (1) + (2) + (3)”: With booms (4) and (5) retracted, booms (2) and (3) are fully extended.
“Boom (1) + (2) + (3)” is to apply to crane operation with boom (3) extended even if only slightly.
