Crane, hoist and related plant operators

13.1%
ADI · 338th of 433 · 95% interval 5.5–22.7

An AI agent can at least partly carry out 13.1% of the task time of crane, hoist and related plant operators, and finish 0.0% alone. The barrier that holds most of the rest back is access to the systems the work runs on.
