What is the function of outriggers on a crane?

The function of outriggers on a crane is to provide stability and support by leveling the crane when it is set up for operation. Outriggers extend horizontally from the base of the crane to distribute its weight more evenly, which helps to prevent tipping over when lifting heavy loads. By ensuring that the crane is stable and level, outriggers enhance safety during operation, especially on uneven ground.

While other options touch on aspects related to crane operation, they do not accurately describe the primary function of outriggers. Lifting heavy loads, operating the boom, and increasing load capacity pertain to other crane mechanisms and characteristics, but they do not encapsulate the essential role that outriggers play in ensuring the crane remains stable and safe while performing its tasks.
