About the crane MB-45

The MB45 is a relatively versatile telescopic crane suitable for any film set or TV studio as this crane has the same dolly ‚footprint’ as the smaller MB30 crane. It is universal to work with and depending on the type and weight of camera package carried it is possible to modify the length and reach of the arm from 35 feet to 45 feet in a matter of minutes.
