In a pick and carry operation, the rated tipping capacity of a crane is based on what percentage?

In a pick and carry operation, the rated tipping capacity of a crane is generally based on 75% of the rated capacity of the crane. This percentage takes into account the additional stresses and potential instability introduced when a crane lifts a load and simultaneously moves or carries it.

When a crane is in a stationary position, its tipping capacity can be calculated based on the full rated capacity. However, as soon as the crane begins to move while carrying a load, the dynamics change, and the risk of tipping increases. The 75% figure is established as a safety margin to ensure stability during the handling of loads in this manner.

This practice safeguards against the risk of tipping, addressing the need to account for both the load and the crane's operating conditions, thereby enhancing the overall safety of crane operations.
