How do you calculate safety factor for lifting? The safety factor for lifting is the ratio between force applied to a component in a system, and the minimum breaking strength of the component. The safety factor is calculated by dividing the minimum breaking strength of the gear by the maximum force that can be supported by the lifting gear. If the safety factor is less than 1, it implies that the force exceeds strength, and the component would fail. When it comes to the estimation of maximum force, riggers can use maximum static force or maximum dynamic force. The former refers to the force when the system is motionless, and the latest refers to the force generated when a falling load is caught. Safety factors are calculated based on status loads. This makes it easier to calculate static forces in the field. Rescuers ensure that systems can accommodate dynamic loads using sufficiently high safety factors. For instance, a component with a static safety factor of 10:1 encounters dynamic events that generate forces five times more than expected, making the dynamic safety factor ratio 2:1. Grip strength, sometimes overlooked, can have an effect on the safety factor of the lifting gear. Strength of manufactured equipment is well tested and accurate - if gear is maintained and inspected on a regular basis, the strength estimates required might weaken the gear. This could include knots, sharp edges that could cut ropes or even a cross-loaded carabiner. However, the strength of anchors connected to certain objects are difficult to estimate. These components are selected on site without testing. Anchor strength estimates must therefore be conservative. Minimum strength estimates can be accurate if conservative estimates for anchors, rope strength adjustments for knots, use of sufficient edge protection and consideration of rope angles are made. Maximum force is more difficult to estimate than minimum strength. It involves accurate estimation of the gear being lifted, in addition to rope angles that can increase forces. The effects of friction are also not meant to be neglected, which can increase or decrease forces, while raising or lowering. Optimum safety factors ensure that systems are stronger than the forces encountered. An increase of safety factors beyond this does not enhance safety. An increase of safety factors of individual components beyond the system’s lowest safety factor does not contribute to lifting gear strength.
