i think i need a spring energy-storage mechanism. Maybe a very large
wind-up clock motor?

the scenario is: a slightly-valuable commodity originates at the top
of a mountain. More or less a bushel at a time. there is an existing
paved road. the commodity fetches a price, but not enough to pay for
very much transport.

A Flying fox. Used in Italy to get supplies to and from mountain tops.

Two cables, one pulley, two carriers and a long bit of rope.
