What function do staypoles serve on an extending ladder?

Stay poles serve the essential function of stabilization for an extending ladder. When an aerial or extension ladder is deployed, stay poles help to secure the ladder in place, preventing it from swaying or tipping over once it is extended to a significant height. This stability is critical, especially during firefighting operations where firefighters might be on the ladder performing rescues or conducting work.

The use of stay poles allows for a safer ladder operation, as they provide additional support and anchorage to counteract the forces that can act on the ladder, such as wind or the movement of personnel on the ladder. Their role is vital for ensuring that the ladder remains rigid and stable, enabling firefighters to work effectively and safely at elevated positions.
