What the thread found

• A steadicam arm post can fail due to metal fatigue even when the operator has successfully handled heavier cameras on previous occasions.
• An Aaton 35-III camera exceeded the structural limits of a steadicam rig after multiple rehearsals, causing the arm post to break during actual filming.
• A handheld-on-dolly setup can serve as an alternative when steadicam operation becomes unsafe, though the visual effect differs from true steadicam work.

Depends on

• The incident occurred on a specific steadicam rig whose model and age are not stated, so the failure threshold may not apply to other equipment.
• Metal fatigue progression is unpredictable and depends on rig condition, maintenance history, and usage patterns.
• The operator had successfully used heavier cameras prior to this incident, suggesting rig-specific rather than general weight-limit issues.
