Hi,
i tried drawing a jib from memory. concepts are roughly similar across.
starting from left,
the yellow is a control plate attached to swivel plate (Green)
Its is connected via a tension cable / rod (Pastel blue) to the front to mantain level. ( see above response to hutchphd)
Red is the bar...
It seems the pulley has springs to have increased torque depending on the length. A jib does not have spring mechanism, both heads are free. Given a scale lever, would it be possible to change the "level condition" to be flexible?
Given the case does it mean i would be able to balance this level scale so that it can stay in any position without changing the weight or distance? if so how?
Thanks Hutchphd,
moment arms are static. they do not lengthen or shorten while going up or down.
There is no spring mechanism from the camera head side to vary torque at different angles too.
The cables are meant to act as a tension cable to level the camera head. Its based on fig 1: the sum of...
Hi, I am trying to understand how camera jibs work.
They seem to be able to remain at whatever angle despite being balanced. The counter weight is static and does not move, yet the jib does not remain level nor does lift or drops. I have spoken to the operators and they mention they don't use...
