That's similar to 254's arm, in that it is a multi-stage, continuous lift.
If I understand MikeD's post correctly, 233's multi-stage arms are essentially cascaded lifts, but the second stage does not return to the original power source (and is instead driven "passively" by a sprocket that is turned as the first stage extends).
The key difference for both arms is that all the stages are nested within each other, which presents numerous challenges and advantages.
