The same hoist frames are used to pick invalids up off beds and down into wheelchairs, baths, etc.

I passed on buying a used one for $50 several years ago, then bought an even nicer used one for $36.

Medicare buys new ones for invalids when the patient gets a prescription from an MD saying one is needed, at a cost from $1200 to $2800.

The workmanship on the medical ones seems better to my eye than the typical engine hoist.
