[SML] Genie lift safety

[Dougherty, Jim]

As a counterpoint, our Genie GR-20 has no outriggers, is self-propelled
and is capable of motion while elevated (per the manufacturer, no
workarounds necessary or desired).  It automatically lowers the travel
speed once elevated.  This unit is the tallest one (@ ~20¹) in that
product line, though, so it won¹t work for every venue.  Loading it on and
off a truck would require ramping or its own forklift.  It¹s a fine unit;
my only gripe being that you need to power it up every time you want to
move it.
