A month or so back, someone put up a picture of a hoist used for transferring stone from a narrow gauge wagon to a standard gauge wagon. The picture was somewhere in North or mid Wales, but I haven't been able to find it again. Fairly simple, a couple of beams mounted on two stone piers, with some form of travelling mechanism to move from side to side.
The piers, beams and traveller I can do, where I'm stuck is finding the pulley wheels to move the traveller from side to side, and something to do the lifting, probably a set of chain blocks. The intention is that the traveller will move, but I suspect that getting the chain block to work is getting a bit too adventurous.
Any suggestions on where to source the parts ? Internet searches so far have drawn a blank.
