Block and tackle
A pulley block set is very useful when hoisting an animal as heavy as an alpaca (60-75kg). Without it I would not be able to do the job. I also have a higher gantry than for sheep for hoisting the pulley block. It means that I can work on an alpaca with its neck on should I choose to do so. You can see the difference in height of the two gantries (the lower one is for sheep).
