We used to do that a lot for museum stuff - but the
problem there is that
some of the bigger machine cabinets only fit on the tail-lift with an inch
or so to spare - we were always paranoid that one was going to just drop
straight off the back.
This can be scary, but there are a couple of tricks to use. One, if
the liftgate has chains that go up at an angle from the back of the
liftgate to a few feetup each side of the back of the truck, one can
stick a board or load brace across the liftgate platform just against
where the chains meet the platform. If the load starts to roll down
the platform, it will hit this and stop. Or, two, simply strap the
load down to the platform, all the way around, just remembering to
strap it so the latch is to the side and not pinned down when the
platform is on the ground.
Ramps seem a bit better *if* you've got the
necessary cables/straps to
safely cope with the distance/weight.
I never use ramps anymore, unless the load consists of small things.
And Dave REALLY needs to invest in some cumalongs.
