What is the typical stability percentage of a crane operating on outriggers?

The typical stability percentage of a crane operating on outriggers is 85%. This percentage represents a balance between the crane's ability to safely handle weights and the dynamic factors such as wind and load movement. Operating on outriggers significantly increases the stability of a crane by widening its base of support, which is critical in ensuring that the crane does not tip over during operation.

Crane stability is calculated by analyzing the crane’s center of gravity and the overall geometry of the setup. An 85% stability percentage suggests that the crane is capable of withstanding a variety of external forces while maintaining safe operation. Ensuring that a crane achieves and maintains this stability percentage is vital for the safety of the operation and the personnel involved.

Higher stability percentages, such as 90%, may be seen in certain configurations or specialized cranes but are not typically represented as standard for all cranes. The standard of 85% is derived from industry practices and safety considerations in crane operations.
