Every lift starts with the same fundamental question: To answer this, engineers look at several key variables: 1. Load Weight and Center of Gravity (CG) If the CoG is miscalculated, the load may
Determining the exact point where a load is balanced is the first step. If the CoG is miscalculated, the load may tilt or swing unexpectedly when lifted.
