Troubleshooting popping motion in the first segment of a G-50x camera crane arm during boom movements
What the thread found
- The first arm segment of a G-50x can exhibit popping or jerky motion during boom up and down movements when the ride isolation adjustments between segments are not properly balanced.
- The inner arm segment closest to the body carries more weight and should have more threads showing in its ride adjustment compared to the outer segment nearest the sled.
- Starting with fewer threads visible in both ride adjustment sections and then adjusting according to load weight can resolve popping issues.
- The lift adjustment for both arm sections should be set to float each segment at roughly the same angle, with a slight upward angle as a starting reference point.
- Operator posture, such as leaning back, can affect arm behavior during boom movements.
- Checking and adjusting the turret screw beneath the lift knob may resolve popping in some cases, though it was not the cause in this instance.
Depends on
- The solution was confirmed effective by the original poster but represents a single case outcome.
- The specific thread count numbers for ride adjustments were not provided.
- The relationship between load weight and optimal thread settings was described only in general terms.
- Operator posture effects were mentioned but not demonstrated as relevant to this particular issue.
