Now look at the sketch below which illustrates how the crane with boom
might be loaded. Assume that the crane weighs 75,924 pounds and that the
50foot flatcar has a load limit of 114,000 pounds. Truck centers are 40
feet apart. Dividing the weight of the load by the load limit gives you the
percentage of load limit. Thus:
75,924 + 114,000 = .666 or 66.6 percent.
As you know from the previous diagram, the CG of a 66.6 percent load must
not be closer to either truck center than onefourth of the distance between
truck centers. In our example, onefourth of 40 feetthe distance between
truck centersis 10 feet. Is the crane in
