What is the purpose of using outriggers on a crane?

Outriggers are an essential component of crane operation, primarily designed to increase stability and prevent tipping. When a crane is set up for operation, particularly on uneven ground or when lifting heavy loads, the outriggers extend outward from the base of the crane. This extension provides a wider support base, distributing the weight more evenly and lowering the center of gravity.

By increasing the crane’s stability, outriggers help mitigate the risks associated with lifting loads, especially when the crane is in operation with a significant load at height or at an outreach angle. The added support provided by the outriggers helps ensure that the crane remains upright and secure, significantly enhancing safety during lifting operations.

Other options, such as supporting extra storage or assisting in loading and unloading materials, do not reflect the primary function of outriggers. The capability to reach higher areas is also unrelated, as that depends on the crane's design and boom configurations rather than the function of the outriggers themselves.
