USING THE CAPACITY CHART
The capacity chart for this crane is located on the inside of
the operator’s cab to the right of the seat. The chart provides
maximum loads that can be safely lifted and give conditions
under which these maximum lifts can be made.
Determine Operating Status
Operating radius is the distance from the centerline of
rotation to the center of the hook block or the downhaul
weight, depending on which is installed.
Located on both sides of the boom is a indicator that gives
the angle at which the boom is positioned (Figure 4-1). This
angle along with the amount the boom is extended can be
applied to the range diagram in the Load Rating Chart to
determine the approximate lifting operating radius of the
boom. For example, if the boom is at a 60° angle and is fully
extended with the 4th section extended, the lifting radius is
approximately 23 feet (7 m). See sample chart in Figure 4-3.
NOTE: To determine the exact lifting radius, use a tape
measure and measure from the center rotation of
the mast to the center of the hook on either the
hook block or the downhaul weight, depending on
which one is installed.
Determining Lift Capacity
Lift capacity is the weight that can safely be raised or lowered
by the crane. It is determined by two factors; structural
strength of the boom and boom extension, and crane
stability.
Located on the Load Rating and Range Diagram Chart are
the Main Boom Load and Boom Extension Ratings. Find the
approximate radius in the chart. Always use the next highest
radius if the actual radius is not on the chart. Read across the
line to the appropriate column to determine what can be lifted
at that radius.
NOTE: Exceeding the capacity is dangerous and voids the
crane’s warranty.
