Jimmy Jib Lens Height
Lens height, this is the maximum, with everything set to specifically to give this, including over-slinging the arm.
In reality for most working operations it is a lot lower, the head is normally under-slung (this makes the lens height some 4 feet lower) and the tripod is not usually at its highest, as this makes the rear end too high to operate if the camera is at ground level.
For 6ft to 12ft Jib requires a 6 foot radius. To swing 180 degrees requires 6ft X 12ft and 360 degrees a 12ft X 12ft
For 15ft to 24ft Jib requires a 9 foot radius. To swing 180 degrees requires 9ft X 18ft and 360 degrees a 18ft X 18ft
For 30 to 40 ft Jib requires a 12 foot radius. To swing 180 degrees requires 12’ X 24’ and 360 degrees a 24’ X 24’
