Load center is the point where the weight of the load is concentrated during lifting operation.

• It is the point where the weight of the load is concentrated

• It is important to know the load center to ensure safe lifting operation

• The load center varies depending on the shape and size of the load

• Incorrect load center calculation can lead to accidents and injuries

Load lifting capacity decreases as radius increases.

• The load lifting capacity is inversely proportional to the radius.

• As the radius increases, the load lifting capacity decreases.

• This is because the load moment arm increases with radius, making it harder to lift the load.

• For example, a crane with a longer boom has a lower load lifting capacity than a crane with a shorter boom.
