You can nest (telescope) two pieces of square tubing, as is done in,
for example, a Harbor Freight "shop crane" aka "engine hoist". Drill
some holes for a holding pin. Add a wider flat on the bottom of both
parts so that you can have a trolley. In the case of those flats,
obviously, you would need to remove and insert the thinner tube with
every use, instead of telescoping.

In most cases, a winch and a set of ramps would work well also.

I need to avoid a possible drop hazard so it must remain a unit. The
addition of a flat may come in handy as far as support for the cantilevered
piece.

Thanks
