What are jib radius and load moment, and why are they important?

The jib radius is the horizontal distance from the tower's center of rotation to the hook. The greater the radius, the less weight the crane can lift.

The load moment (t*m) is the product of the load weight (t) and the jib radius (m). It is the main characteristic that defines the crane's power.

Correctly calculating these parameters is crucial for safety and efficiency, as they determine whether the crane can cover the entire construction area and lift the necessary materials.
