What is the maximum percentage of a crane's net capacity allowed when lifting with more than one crane?

When lifting with more than one crane, it is critical to adhere to safety regulations and operational guidelines to prevent overload and ensure stability. The maximum percentage of a crane's net capacity allowed in such situations is set at 75%. This figure is established based on risk management studies and industry standards, which take into account the complexities and dynamics introduced when multiple cranes are involved in a lift.

By limiting the load to 75% of a crane's capacity, operators can account for various factors such as the potential for load movement, shifting, and the different dynamics that arise when coordinating the actions of multiple cranes. This margin is essential for maintaining the integrity of both the cranes and the safety of personnel involved in the operation.

Using a percentage lower than this threshold helps to manage the added stresses on the cranes and reduces the risk of failure. It also aids in ensuring that the lifting operation remains within the safe working limits, thereby enhancing overall operational safety and efficiency.
