NOAA brings a mobile unit to Gary L. Kranz for a little straightening
out. Unit has a radar dish mounted on top of the trailer for tracking satellites
and required that the mobile unit be as level as possible. The unit was used
in all kinds of terrain and needed a system to level the unit. A design was
used where four hydraulic cylinders were used to lift the unit to a level
position.
Each hydraulic cylinder had its own "level bubble", and
the hydraulic system would turn off when the unit reached a level point. When
the unit was transported, the hydraulic cylinders simply folded up and were
stored. A master "level bubble" mounted inside of the unit could
be operated by push button control. When the operator achieved a level position,
the hydraulics locked all cylinders to prevent movement.
