Neil...
If you know the loads involved it's easy enough to figure out if the chain can handle it.
Figure 10 lb as the break strength and you should be safe. You can also double the sprockets on the same shafts, but be very careful about aligning the teeth.
Further OT..
At one time I was toying with the idea of building a chain drive wall clock. A cheap quartz movement would drive the second hand either direct or thru a chain and two 60:1 reduction trains driving coaxial tubes for the minute and hour hands. It would all be carried in Lexan frame plates like the winder. The only limit is how whimsical and artistic I'm capable of getting. Wear on the coax tubes wouldn't be an issue as there are no side loads the way there'd be with gears, only the weight of the tubes within each other, and a drop or two of oil would take care of that.
May still do it.
Art.
