I couldn't get the link to open, but I found this which I think is the same
thing, if this link works ;-)

The other possible option is those ladders made up of 4 x 4 rung sections.
You can either put them up as an inverted 'w' with the board across the
two (like a scaffold board) - which would give you more height to start
with. Or, they can be set like an an inverted 'v'where one of the legs of
the inverted 'v' carries on over the top of the other. These are designed
to allow access almost from above - and often used for cleaning roofs of
vans, etc.

Trouble is, its more expense (but useful for a number of other things).

Rather than imagine inverted 'v's, have a look at:
