The allows to study a winch concerning its lifting velocity and its load transmission. Additionally, the functioning of a back-run safety device is demonstrated. Load transmission and efficiency can be determined by force equilibrium. Both rope drums are ball-bearing mounted. The forces are generated by sets of weights and can be quickly and easily varied.
1. Study of a winch
2. Drum and driving wheel made of aluminium, gear wheels made of POM
