Why are load calculations important before a lift?

Load calculations are critical before a lift because they ensure that the equipment being used can safely handle the weight being lifted. Safety is paramount in rigging operations, and knowing the exact weight of the load allows for the correct selection of machinery and rigging gear, such as hoists, cranes, and slings, which have specific weight limits. If the load exceeds these limits, the equipment risks failure, potentially leading to catastrophic accidents, injuries, or fatalities. Additionally, understanding the load's specifications helps in evaluating the center of gravity and dynamics of the lift, which are essential for maintaining stability throughout the operation.
