What the thread found

• The Arri Alexa paired with a Pace 3D twin camera rig was used for steadicam work on the 2011 film Hugo
• A PRO arm steadicam rig achieved approximately 77 pounds of payload capacity, while a G70 arm maxed out around 75 pounds
• The PRO arm skeleton design can potentially support 90 to 100 pounds safely if appropriate springs were manufactured for that weight class
• A prototype Flyer arm hand-built by a manufacturer held approximately 29 pounds of payload
• Original Flyer arm springs rated for 15 pounds camera payload could comfortably lift 32.5 pounds, though operators typically stayed below 20 pounds to avoid excessive stress on the rig
• A Flyer arm spring broke due to external damage rather than reaching maximum weight capacity
• The PRO arm has a higher weight capacity than previously stated web specifications suggested

Depends on

• Payload capacity comparisons rely partly on unverified web specifications and operator estimates rather than official manufacturer data
• Comments about theoretical maximum capacities for the PRO arm skeleton are based on material analysis and design observation rather than engineering testing
• Limited hands-on experience with some equipment by discussants providing estimates
• Specifications for prototype and earlier generation equipment may not reflect current production standards
