الحد الأقصى للقدرات على الحمولة والحدود التي يفرضها غيمبل ماكس EFP لتثبيت الكاميرا
مضى على هذا 17 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- The EFP gimbal was designed specifically for video cameras and is rated for a maximum payload of 39 pounds or approximately 17.5 kilograms
- The EFP gimbal uses cast construction while the more capable 3A gimbal uses machined construction, making the EFP gimbal intentionally weaker
- Early EFP models with blue springs handled 12 to 24 pounds, while later models with black springs handled 24 to 39 pounds total payload
- Using film cameras like an ARRI 535 on an EFP gimbal exceeds the rated capacity and risks structural failure from accumulated stress and hair fractures in aged equipment
- The EFP gimbal and 3A gimbal share similar external appearance but differ significantly in internal construction and load capacity by design
- Upgrading individual components like the arm or vest does not increase the gimbal's load capacity, as the gimbal itself remains the weakest link
- Alternative gimbals such as the BFX ACME gimbal can be retrofitted to EFP rigs and handle larger camera weights while maintaining compatibility with the standard 1.50 inch post
- A carbon fiber post can replace the original EFP post if the original becomes out of round from use
يعتمد على
- The EFP was intentionally manufactured with reduced capacity compared to the 3A model to maintain market differentiation and pricing strategy
- Most EFP units in circulation have experienced decades of use and potential abuse, introducing structural weaknesses not present in new equipment
- Information reflects gimbal design practices from the 1990 era and earlier EFP models
- User reports of successfully carrying heavier cameras represent extreme use cases and do not validate safe operating practice
- Horizontal balance positions with heavy cameras create additional stress that may accelerate gimbal failure
