Center of Gravity

There are some pretty complicated explanations of the center of gravity of a load. Complex mathematical ways are available to determine the center of gravity of any load. As riggers, all we care about is where the load's center of gravity is located.

Why Is The Center of Gravity Important? 
Balanced lifts are inherently more stable in flight. Knowing the location of the center of gravity of a load is important in order to make a balanced lift.

Simple Definitions 
The center gravity of a load is the single point on the load at which it can be hoisted perfectly balanced. Some riggers like to think of it somewhat in reverse: it is the point at which all of a load's weight is concentrated. When performing a lift, they see it as counteracting this concentrated weight at exactly the right spot.

It Is Not Rocket Science 
Sometimes finding the correct pick point for a load, or in other words, the center of gravity, is pretty simple. A load that is uniformly consistent in cross section along its length will have its center of gravity located exactly half the length of the load. This is because uniform cross sections result in uniformly distributed weight.

How to Find the Center of Gravity by Trial and Error
Lifting problems can arise when loads have unevenly distributed weight. When it is obvious that the load does not have uniformly distributed weight, the following step by step method can be used to locate the center of gravity by trial and error:

Loads Rotate Around Their Center of Gravity 
It is a known fact that loads, given the opportunity, will rotate around their center of gravity. This leads to some simple, but important, hoisting rules.
