5.3 RATED TOTAL LOAD CHART
• Rated total load chart is based on that the crane is placed leveled and on firm ground.
Depending on the outrigger setting or bad ground conditions the machine may tip
over. Be very careful during the work.
• The rated total load in the chart is based on actual working radius with deflection
which occurs in the boom under load.
• If boom (3) is extended to some extent, work should be performed in accordance with
the performance given in the “Booms (1) + (2) + (3)” column.
• If boom (4) is extended to some extent, work should be performed in accordance with
the performance given in the “Booms (1) + (2) + (3) + (4)” column.
If more than half of the “ mark” is exposed from boom (3), work should be
performed in accordance with the performance given in “Booms (1) + (2) + (3) + (4) +
(5)” column.
• If working radius exceeds the value of Working Radius column in the chart by any
extent, work should be performed within the rated total load in the next column of
Working Radius.
• The rated total load includes the mass of a hoisting attachment (weight of hook: 90
kg).
• Unless the outriggers are extended to maximum, work should always be performed in
accordance with the values in “Rated total load chart for outrigger extended to other
than maximum”.
