What action should be taken if a crane’s outrigger floats are unstable?

When a crane's outrigger floats are unstable, leveling the crane is crucial for ensuring safety and stability during operation. Outriggers are designed to distribute the weight of the crane and provide a solid base. If they are not stable, it can lead to a dangerous situation where the crane may tip or become unbalanced, especially when lifting loads.

By leveling the crane, you ensure that all outriggers are evenly positioned and functioning as intended. This action allows the crane to operate safely and efficiently, reducing the risk of accidents. It's a fundamental step that should be taken before proceeding with any lifting operations to maintain proper center of gravity and prevent potential hazards.

In contrast, increasing the load, adjusting boom length, or increasing the height of the outriggers may exacerbate the instability and lead to dangerous conditions. Therefore, taking the time to level the crane appropriately is the correct and safest course of action.
