The most critical step in any rigging operation is determining the weight of the load to be hoisted. If this information is not available from shipping papers or design plans, it must be calculated. Equally important is locating the Center of Gravity. The crane hook must be positioned directly above the CoG to ensure the load lifts level and true.

Rigging engineering isn't just about picking up a load; it's about understanding the forces involved. Proper calculations ensure:
