CAPACITY CHART INFORMATION
F2081-16
OPERATING RADIUS
OPERATING RADIUS is the horizontal distance from the
crane’s centerline of rotation to the center of the freely
suspended load line or load block.
The centerline of rotation is difficult to locate. Therefore,
deduct the radius (R) given in the table from the operating
radius given on the capacity chart. Then measure from the
point indicated in the appropriate illustration to the center of
the load line or load block.
This practice will eliminate the need to find the crane’s
centerline of rotation when measuring operating radius.
