A Verification of Competency (VOC) is a formal assessment process that confirms a crane operator can competently and safely operate specific plant machinery—in this case, a 100 ton slewing crane. Slewing cranes rotate on a vertical axis and are commonly used in heavy construction, mining, and infrastructure projects.
A VOC isn’t a training course—it’s a skills test. If you’ve previously received training or hold a license, the VOC validates that you can still perform the task to current standards. It’s a requirement for many employers, especially on Tier 1 and government worksites.
